How to Make a Server in Eaglercraft 1.12.2 Exclusive

Eaglercraft is a lightweight, browser-friendly reimplementation of Minecraft: Java Edition that allows servers and clients to run in constrained environments. Making an Eaglercraft 1.12.2 server “exclusive” means limiting who can join — for example, allowing only invited players, a whitelist of accounts, or authenticated users from a specific source — while preserving a smooth player experience. This essay explains the goals, technical options, step-by-step setup, recommended configurations, maintenance, and security considerations for creating an exclusive Eaglercraft 1.12.2 server.

Goals and exclusivity models

• Controlled access: Only specific players may connect.
• Usability: Invitations and join flow should be straightforward.
• Security: Prevent unauthorized access and reduce attack surface.
• Manageability: Admins should easily add/remove users and audit joins.

Common exclusivity models

• Whitelist by username: Only preauthorized Minecraft usernames (or Eaglercraft account identifiers) can join.
• Token/invite-based access: Players receive a unique code or link to authenticate and join.
• IP-restricted or VPN-only access: Only connections from specific IPs or VPN ranges are permitted.
• Password-protected lobby: A gateway page or server requires a password before proceeding.
• OAuth/third-party auth: Using external identity providers to allow only certain verified users.

Technical components of an exclusive Eaglercraft server

• Eaglercraft server core: The server binary or Node/Java host that implements the Eaglercraft protocol for 1.12.2.
• Web server/gateway: Optional front-end that serves the client and performs pre-connection checks (invite code entry, login).
• Authentication system: Whitelist, token manager, or third-party auth integration.
• Storage: Small database or file for storing allowed users, tokens, and logs (SQLite, JSON, or YAML are common for small servers).
• TLS/HTTPS: Encrypts web traffic and protects tokens/credentials in transit.
• Admin tools: Simple UIs or console scripts for managing invites and the whitelist.

Step-by-step setup (presumes moderate technical familiarity)

1. Prepare hosting environment

   • Choose a host (VPS, dedicated server, or a reliable cloud instance) with Node/Java support and a domain name.
   • Ensure firewall allows required ports (HTTP/HTTPS for web client assets, and the port Eaglercraft uses for WebSocket/connection).

2. Install and run the Eaglercraft 1.12.2 server

   • Obtain the Eaglercraft server build compatible with Minecraft 1.12.2 from a trusted source or the official repository.
   • Follow included instructions to run the server. Confirm the server starts and accepts test connections on the default port.

3. Serve the client through an HTTPS web server

   • Host the Eaglercraft web client files behind an HTTPS-enabled web server (Nginx, Caddy, or Apache).
   • Configure a domain and obtain TLS certificates (Let’s Encrypt is common).
   • Ensure the Eaglercraft client uses the correct WebSocket endpoint to reach your game server.

4. Implement an access control layer Option A — Whitelist by username:

   • Create a whitelist file (whitelist.json or similar) and add authorized usernames.
   • Configure the server to check the whitelist during connection handshake and reject others. Option B — Invite/token-based gateway:
   • Build a small web gateway page served before the client loads. Require users to enter a single-use invite token or password.
   • Tokens: generate cryptographically-random tokens, store them server-side with status (unused/used/expiry).
   • When token validated, set a short-lived session cookie or issue a temporary JWT that the client supplies to the Eaglercraft server during the connection handshake. Option C — OAuth / third-party auth:
   • Integrate OAuth (Google, Discord, etc.) into your gateway. After login, check the user’s account against an allow list or a team/role.
   • Map verified identities to server permissions.

5. Integrate the gateway with the Eaglercraft server

   • If the Eaglercraft server supports custom handshake hooks, validate the session token or cookie at connection time.
   • If not, use a reverse proxy that performs the check and only forwards WebSocket connections that include valid session info.
   • Alternatively, maintain IP-temporary allowances: when a user successfully passes the gateway, record their IP for a short window and allow connection from that IP.

6. Admin interfaces and workflows

   • Provide a simple admin panel (web UI or CLI) to:
     • Generate and revoke invite tokens.
     • Add/remove users to the whitelist.
     • See recent connection attempts and logs.
   • Automate token expiration and cleanup to keep the invite list current.

7. Logging and monitoring

   • Log successful and failed connection attempts, token usage, and admin actions.
   • Monitor server performance and WebSocket connection counts to spot abuse.

Security and operational best practices

• Use HTTPS/TLS everywhere to protect tokens and session cookies.
• Prefer single-use, time-limited invite tokens to reduce reuse risk.
• Sanitize and validate all inputs in the gateway to avoid injection attacks.
• Rate-limit login/gateway attempts and implement basic protections against brute-force attacks.
• Keep the server software and dependencies updated and apply security patches.
• Limit administrative access (SSH keys rather than passwords) and use role-based access for management tools.
• Periodically audit the whitelist and revoke access for users who no longer should have it.
• If using IP allowances, be aware of NAT and dynamic IPs — prefer token/session approaches when possible.

Example minimal configuration choices (practical recommendations)

• Gateway: small Node.js/Express app with HTTPS and simple token store in SQLite.
• Tokens: 32+ byte random values, single-use, expire after 24–72 hours.
• Whitelist file: JSON managed by admin scripts for quick edits and version control.
• Reverse proxy: Nginx to host the client and forward WebSocket connections after validating an Authorization header or cookie.

Troubleshooting common issues

• Clients fail to connect: Check WebSocket endpoint, TLS configuration, and firewall rules.
• Valid users rejected: Verify the server checks the same identifiers (username vs. UUID) as your whitelist/gateway maps.
• Tokens not recognized: Ensure the client includes the session token in the WebSocket handshake headers or query string as your server expects.
• Multiple users from same IP: If relying on IP-based allowances, recognize that shared NAT may block legitimate players; switch to token/session validation.

Conclusion Creating an exclusive Eaglercraft 1.12.2 server requires combining the game server with an access-control layer that authenticates and authorizes players before they enter. The simplest robust approach is a web gateway that issues short-lived, single-use tokens validated by the server at connection time, served over HTTPS, coupled with a small admin workflow for generating and revoking invites. Prioritize secure token generation, encrypted transport, logging, and periodic access audits to maintain both exclusivity and a smooth player experience.

Here’s a step-by-step guide on how to make a server in Eaglercraft 1.12.2 (exclusive) — meaning a server that works specifically with the Eaglercraft client version that emulates Minecraft 1.12.2 in a browser.

Conclusion

Creating an exclusive server in Eaglercraft 1.12.2 involves setting up a new server, configuring its properties, and making it exclusive through whitelist or permission settings. By following these steps, you can create a private and controlled environment for your Minecraft gameplay.

To host an Eaglercraft 1.12.2 server, you typically need to set up a standard Minecraft server and bridge it to the web using a specialized proxy that supports Eaglercraft clients. Quick Setup Method: Eagler.host The simplest way to create a 1.12.2 server is through Eagler.host , a specialized hosting platform. Registration

: Sign up with your email and verify your account via the link sent to your inbox. Server Creation : Select "create a new server" in the panel and choose Minecraft 1.12 as your version.

: Agree to the Minecraft EULA and click "start." Copy the provided IP address into your Eaglercraft client to join. Manual Setup (Self-Hosting or VPS)

If you want full control, you can bridge a standard Paper or Spigot 1.12.2 server. 1. Set up the Game Server Download Software PaperMC 1.12.2 (Build #1620) Initial Run

: Put the jar in its own folder and run it to generate files. Set Disable Online Mode server.properties online-mode=false . This allows non-premium (cracked) connections. Add Protection

: Since the server is "cracked," it is highly recommended to install an authentication plugin like AuthMe Reloaded to protect player accounts. 2. Configure the Eaglercraft Proxy

Eaglercraft clients connect via WebSockets, which standard Minecraft servers do not support. You must use a proxy like BungeeCord Proxy Plugin : Install the EaglercraftXServer (or EaglerXBungee) plugin on your proxy server. Protocol Bridging ViaVersion ViaBackwards

to ensure the 1.12.2 server can communicate with various client versions. Proxy Settings : In the proxy's config.yml online_mode is also set to 3. Making it Public To let others join from outside your network: Port Forwarding

: Forward the port used by your Eaglercraft proxy (often 8081 or 25577) in your router settings. Tunneling (Optional) : If you cannot port forward, use services like Secure Connection

: For "wss://" (secure) connections, you may need a domain and a service like Cloudflare Tunnels

Are you looking to host this server on your own computer, or would you prefer a free online host like Aternos?

Creating an exclusive Eaglercraft 1.12.2 server involves bridging a standard Minecraft Java server with a WebSocket proxy to allow browser-based connections. Abstract

Eaglercraft 1.12.2 is a community-driven port of Minecraft that runs in modern web browsers. Unlike standard Minecraft servers that use TCP, Eaglercraft requires WebSockets (WS/WSS) to communicate with the browser client. This guide details the "Exclusive" setup using BungeeCord and the EaglerXBungee plugin to facilitate 1.12.2 gameplay. 1. Technical Requirements

Java Runtime: Java 11 or higher is recommended for 1.12.2, while some Eaglercraft components may require Java 17+. Hardware: At least 4GB of RAM and 10GB of storage.

Network: A public IP for port forwarding or a tunneling service like Ngrok. 2. Core Components Setup

You must run two separate server components: the Backend Server (holds the game world) and the Proxy Server (handles browser connections). Step 1: The Backend (Paper 1.12.2)

Download the PaperMC 1.12.2 (Build #1620) JAR file from the PaperMC build explorer. Run the JAR file, accept the eula.txt by setting eula=true.

Crucial Configuration: Open server.properties and set online-mode=false.

Note: Since these servers are "cracked," it is highly recommended to install the AuthMe plugin for security. Step 2: The Proxy (BungeeCord) Download the latest BungeeCord.jar. In the BungeeCord config.yml, also set online_mode: false.

Download the EaglerXBungee plugin from Lax1dude's GitHub and place it in the BungeeCord plugins folder.

Configure the listeners.yml within the plugins/EaglercraftXBungee folder to point to your backend server’s IP and port. 3. Connectivity & Deployment

Browser players cannot connect to standard ports; they need a WebSocket (WS) address.

Creating an Eaglercraft 1.12.2 server is widely considered the "golden ticket" for browser-based Minecraft because it bridges the gap between classic browser play and modern features like integrated voice chat and smoother performance. Review: Eaglercraft 1.12.2 Server Methods

Software: PaperMC 1.12.2 (build #1620 is recommended for stability).

Plugins: You must have EaglerXBungee installed on your proxy to translate browser traffic into game packets. 2. The "Must-Have" Configurations

To ensure your server is actually reachable by browser clients, you must toggle these specific settings:

Online Mode: Set online-mode=false in both server.properties and your BungeeCord config.yml. This allows "cracked" browser clients to connect.

Authentication: Because online mode is off, you must install a plugin like AuthMe Reloaded or LoginSecurity so players have passwords for their accounts.

Protocol Support: If you want players from other versions to join, add ViaVersion, ViaBackwards, and ViaRewind. 3. Making it Public (WSS vs. WS)

Browsers require Secure WebSockets (WSS) unless you are playing locally.

Easy Way: Use a host like Eagler.host or Sealos which handles SSL certificates automatically.

Manual Way: Use Nginx as a reverse proxy to provide an SSL layer, or use ngrok to tunnel your local port (8081 for Eaglercraft) to a public URL. Final Verdict

Creating a 1.12.2 server is slightly more complex than 1.8.8 due to higher RAM needs and specific plugin versions, but it offers a vastly superior experience for modern browser gaming.

How to Make a Server in Eaglercraft 1.12.2 Exclusive Eaglercraft has revolutionized how we play Minecraft, bringing the full Java experience to the web browser. While version 1.8.8 has long been the standard, the community has shifted toward Eaglercraft 1.12.2. This version offers better performance, more blocks, and a more "modern" feel.

If you want to host a private world for friends or build a community, this guide will show you how to set up an exclusive Eaglercraft 1.12.2 server. 1. Understanding the Architecture

Unlike a standard Minecraft server, an Eaglercraft server requires two main components:

The Backend: A standard Java Minecraft server (Spigot, Paper, or Waterfall).

The Proxy (EaglercraftXBungee): A modified version of BungeeCord that "translates" the web browser’s WebSocket signals into something the Minecraft server can understand. 2. Prerequisites Before starting, ensure you have the following: Java 17 or higher: Required to run the 1.12.2 backend.

A VPS or Home PC: A Linux VPS (like Ubuntu) is recommended for 24/7 uptime.

The EaglercraftXBungee Files: You can typically find these on the official Eaglercraft GitHub or community Discord mirrors. 3. Setting Up the Backend Server

First, we need a "real" Minecraft server for the Eaglercraft proxy to connect to.

Download Paper 1.12.2: Go to the PaperMC website and grab the 1.12.2 build.

Initial Run: Create a folder, place the .jar inside, and run it:java -Xmx2G -jar paper-1.12.2.jar nogui Accept EULA: Edit eula.txt and change false to true. Configure server.properties:

Set online-mode to false. This is crucial because Eaglercraft handles authentication differently. Note the server-port (default is 25565). 4. Configuring EaglercraftXBungee This is the bridge that allows browsers to connect.

Download the Proxy: Search for the "EaglercraftXBungee" 1.12.2 compatible build. Configure config.yml:

Look for the servers section and point it to your Paper server's IP and port (e.g., 127.0.0.1:25565).

Listeners: Change the listener port to something like 8080. This is the port players will use to connect.

Authentication: If you want an "exclusive" server, enable the Auth system in the EaglercraftXBungee config. This forces players to create a password when they first join. 5. Connecting via the Web Client To actually play, you need a web frontend.

Hosting the HTML: You can host the Eaglercraft 1.12.2 HTML file on GitHub Pages, Vercel, or your own web server. Adding the Server: Open your Eaglercraft 1.12.2 client. Go to "Multiplayer" -> "Add Server."

Enter your WebSocket address. It will look like this: ws://your-ip-address:8080. 6. Making it "Exclusive" To keep your server private and secure:

Whitelist: Use the /whitelist on command in your Paper console to ensure only approved usernames can join.

SSL (Optional but Recommended): If you are hosting on a domain, use a reverse proxy (like Nginx) to change ws:// to wss:// (secure WebSockets). Most browsers block non-secure WebSockets on HTTPS sites.

Plugins: Install EssentialsX and a permissions plugin like LuckPerms to manage your player base effectively. Troubleshooting Tips

Connection Refused: Ensure your firewall (UFW on Linux or Windows Firewall) has the ports (8080, 25565) open. How to Make a Server in Eaglercraft 1

Internal Server Error: Check the proxy console. Usually, this means the Paper backend isn't running or the online-mode is still set to true.

By following these steps, you’ll have a high-performance, exclusive Eaglercraft 1.12.2 server ready for your community.

To set up an Eaglercraft 1.12.2 server, you essentially create a standard Minecraft 1.12.2 "cracked" server and connect it to a WebSocket proxy that translates browser traffic into game data. 1. Basic Server Setup

First, establish the foundation of your server using 1.12.2-compatible software like PaperMC.

Requirements: A machine with at least 4GB of RAM and Java 11 or higher installed.

Initialization: Download the 1.12.2 .jar file, run it once to generate files, then change eula=true in the eula.txt file.

Configuration: Open server.properties and set online-mode=false. This is mandatory for Eaglercraft to function. 2. The Bridge (Proxy)

Because browsers cannot connect directly to standard Minecraft ports, you must use a proxy like BungeeCord with the EaglerXBungee plugin.

Install BungeeCord: Download the BungeeCord.jar and run it in a separate folder.

Add Plugin: Download EaglerXBungee and place it in the BungeeCord plugins folder.

Link the Two: In the BungeeCord config.yml, set the backend server address to match your Paper server (usually 127.0.0.1:25565). 3. Making it Public

To allow others to join, you need a WebSocket URL (usually starting with ws:// or wss://).

Port Forwarding: Forward the BungeeCord port (default 25577) and the Eaglercraft listener port (often 8081) on your router.

Tunneling (Alternative): Use services like ngrok or playit.gg if you cannot port forward. For ngrok, run a command to tunnel port 8081.

Quick Hosting: Specialized hosts like eagler.host or Sealos offer one-click templates that automate these steps for you. 4. Connecting

Once running, users join by opening an Eaglercraft 1.12.2 client, clicking Multiplayer > Add Server, and entering your WebSocket address (e.g., ws://your-ip:8081).

To create an exclusive Eaglercraft 1.12.2 server, you must set up a standard Java 1.12.2 backend and bridge it to the browser using a BungeeCord proxy with the EaglerXBungee 1. Set Up the Backend Server

First, build a standard Minecraft server that can handle 1.12.2 connections. : Download PaperMC 1.12.2 (recommended for performance) or standard Spigot. Essential Plugins ViaVersion ViaBackwards

to ensure cross-version compatibility for various Eaglercraft clients. Configuration server.properties online-mode=false

. This is mandatory because Eaglercraft uses its own authentication. 2. Configure the Eaglercraft Proxy

The proxy acts as the bridge, converting standard Minecraft traffic into WebSockets for browsers. Proxy Software : Download BungeeCord : Install the EaglerXBungee plugin (available on Lax1dude's GitHub ). Drop the file into the BungeeCord Exclusivity Settings : In the BungeeCord config.yml online_mode: false Listener Configuration plugins/EaglercraftXBungee/listeners.yml

(or similar config), define the port the browser will connect to (common ports are 8081 or 25577). 3. Enable Public or "Exclusive" Access

To make the server reachable by others while keeping it "exclusive" (controlled access): Port Forwarding

: You must forward the WebSocket port (e.g., 8081) on your router to your PC's local IP. Tunneling (Alternative) : Use services like

if you cannot port forward. These provide a public address for your WebSocket. Authentication (Exclusivity)

: To keep the server exclusive to specific players, install an authentication plugin like

on the backend server. This requires players to register and log in with a password. 4. Connection Details

Once running, players join your server by entering your WebSocket address in the Eaglercraft Multiplayer menu: ws://YOUR_IP:PORT (unencrypted) or wss://YOUR_DOMAIN (encrypted). or setting up a custom domain for your server? Controlled access: Only specific players may connect

🛠️ The Checklist (Don't skip this!)

Before we touch code, you need the right tools. Since this is Eaglercraft, you can't use standard Minecraft server jars directly. You need the bridge.

1. Java Runtime Environment (JRE): Make sure you have Java 8 or higher installed on your PC.
2. The Server Software: You need "EaglercraftX 1.12 Server" (often found via reputable community discords or GitHub repositories).
3. A Brain: You’ll need to know how to port forward (or use a tunneling service like Playit.gg if you can’t).

Step 2: Run the Server for the First Time

Open a terminal or command prompt:

• Windows: Shift + Right-click inside the folder → Open PowerShell/CMD here.
• macOS/Linux: cd ~/Desktop/EaglerServer in terminal.

Then run:

java -jar EaglercraftServer_v1.12.2.jar

The server will generate several files:

• server.properties (same as vanilla Minecraft but with some Eaglercraft-specific lines)
• whitelist.json
• ops.json
• A world folder

When you see Started websocket server on 0.0.0.0:8081, your server is live.

Important: Eaglercraft servers run on WebSocket ports (usually 8081), not standard TCP 25565. This is a common point of confusion.

Step 6: Starting the Server

1. Review your server settings to ensure everything is configured correctly.
2. Click the "Start" or "Create" button to start your server.

Example admin workflow

1. Player requests access.
2. Admin runs: whitelist add PlayerName
3. Player launches Eaglercraft 1.12.2 client, connects to server IP:port, joins successfully.
4. To revoke: whitelist remove PlayerName

If you want, I can:

• produce the exact start scripts and example whitelist.json template,
• suggest a plugin/mod for password-on-join (if you tell me which server build you’re using), or
• provide firewall commands for a specific OS. Which would you like?

Eaglercraft has revolutionized how players access Minecraft by bringing the full Java Edition experience directly to web browsers. With the release of the 1.12.2 version, many enthusiasts are looking for ways to host their own private worlds. This guide provides a comprehensive walkthrough on how to create a high-performance Eaglercraft 1.12.2 server from scratch. Understanding the Eaglercraft Architecture

Creating an Eaglercraft server is different from setting up a standard Minecraft Java server. Because browsers cannot communicate directly with standard Minecraft server protocols, you must implement a proxy system. This setup typically involves three main components: a standard Minecraft 1.12.2 server (usually Paper or Spigot), an Eaglercraft-compatible proxy (like EaglercraftXBungee), and a web server to host the client files. Prerequisites and System Requirements

Before you begin, ensure your hardware can handle the load. For a small group of friends, a VPS or local machine with at least 4GB of RAM and a modern dual-core CPU is recommended. You will need to install the Java Development Kit (JDK) 8 or 17, depending on your specific proxy choice, though JDK 11 is often the sweet spot for 1.12.2 stability. Additionally, you should have a basic understanding of using a terminal or command prompt. Step 1: Setting Up the Backend Server

The heart of your operation is the actual Minecraft server. Download the Paper 1.12.2 jar file from the official archives. Paper is preferred over vanilla because it offers significantly better performance and plugin support. Create a folder named "Backend," place the jar inside, and run it once to generate the eula.txt file. Open this file and change "eula=false" to "eula=true."

Restart the server to generate the configuration files. Once loaded, stop the server and open the server.properties file. You must set "online-mode" to "false" because the Eaglercraft proxy will handle authentication and data translation. Step 2: Configuring the Eaglercraft Proxy

The proxy is the bridge that allows browser clients to connect. The most popular choice is the EaglercraftXBungee fork. Download the latest release and place it in a separate folder named "Proxy." Run the proxy once to generate its configuration files.

In the config.yml file of your proxy, you need to point it toward your backend server. Locate the "servers" section and ensure the address matches your backend server's IP and port (usually localhost:25565 if they are on the same machine). Most importantly, find the listeners section and set the port to something like 25577. This is the port your web client will eventually connect to. Step 3: Implementing WebSocket Support

Eaglercraft requires WebSockets to function. In your proxy configuration, you must enable the Eaglercraft listener. This involves specifying a WebSocket port (often 8081). If you plan on making the server public, you should also look into setting up an SSL certificate via Nginx or a similar reverse proxy, as many modern browsers block unencrypted WebSocket connections (ws://) on encrypted sites (https://). Step 4: Hosting the Client Files

Players need a way to access the Eaglercraft client. You can host the 1.12.2 HTML client files using GitHub Pages, Vercel, or your own Nginx web server. Once you have the HTML file, you may need to edit the internal configuration (usually found in a script tag within the HTML) to point to your proxy's WebSocket address. Step 5: Testing and Troubleshooting

Start your backend server first, followed by the proxy. Open your browser and navigate to your hosted client. Enter your server's WebSocket address in the multiplayer menu. If you cannot connect, check your firewall settings to ensure the WebSocket port is open. Common issues include version mismatches between the proxy and backend, or incorrect IP addresses in the configuration files. Final Optimization and Management

To enhance the experience, consider adding plugins like EssentialsX or LuckPerms to your backend server. Since Eaglercraft servers often run in offline mode, it is vital to install an authentication plugin like AuthMe Reloaded to protect player accounts. Regularly back up your world folder and configuration files to prevent data loss.

By following these steps, you will have a fully functional Eaglercraft 1.12.2 server. This setup provides a seamless bridge between modern web technology and the classic Minecraft experience, allowing anyone with a link to join your world without needing a standalone game launcher.

To make a private Eaglercraft 1.12.2 server, you must run a standard Minecraft 1.12.2 Paper or Spigot server with online-mode set to false. You then connect it to an Eaglercraft proxy like EaglerXBungee or EaglercraftXServer to translate the game's protocol into WebSockets for browser access.  🛠️ The Architecture 

Eaglercraft isn't a standalone server. It is a "translation layer" that sits between your browser and a real Java Minecraft server. To get 1.12.2 running, you need three main components:  The Engine: A Java server (Paper 1.12.2).

The Translator: A proxy (BungeeCord or Velocity) equipped with the Eaglercraft plugin.

The Bridge: A tunneling service (like Ngrok or Cloudflare) to make your local WebSocket public.  🚀 Step-by-Step Setup  1. Set Up the 1.12.2 Backend  Download: Get the Paper 1.12.2 server JAR.

Initial Run: Launch it once to generate files, then stop it.

Crucial Change: Open server.properties and set online-mode=false. Eaglercraft uses its own authentication, so Mojang's session check must be off.

Compatibility: Add ViaVersion, ViaBackwards, and ViaRewind to the plugins folder so different client versions can connect seamlessly.  2. Configure the Eaglercraft Proxy 

The proxy is the "face" of your server that browsers talk to. 

Install Bungee: Place the BungeeCord.jar in a separate folder.

Add the Plugin: Download the EaglercraftXServer or EaglerXBungee JAR and put it in the proxy's plugins folder.

Edit Config: In the proxy's config.yml, set online_mode: false.

Link Servers: Ensure the proxy is set to forward connections to your 1.12.2 backend server's port (usually 25565).  3. Making it Public (The "Exclusive" Part) 

Standard Minecraft uses TCP, but browsers use WebSockets (ws:// or wss://). 

Local Access: You can join via your IP on port 8081 (default for Eaglercraft).

Public Access: Use Ngrok to tunnel port 8081. Run the command ngrok http 8081 to get a public URL.

Exclusive Privacy: To keep it private, use an authentication plugin like AuthMe Reloaded or LoginSecurity so only players with a password you've provided can play.  🌐 Hosting Alternatives 

If you don't want to host on your own PC, consider these automated options: 

Eagler.host: A specialized provider that offers a "one-click" setup for Eaglercraft servers up to version 1.12.

Sealos: Offers pre-configured Eaglercraft templates that automate the SSL certificate and WebSocket setup.
