The error message "Connection to the game failed" in Sniper Elite 3 (often followed by "top" in server logs or player reports) typically points to a network or multiplayer connectivity issue, not a story-related problem. The "Connection to the game failed" error in

However, since you mentioned "story" — if you’re asking whether this error is part of the single-player campaign’s narrative or a story mode feature:

  • No, it’s not a story element. The single-player campaign in Sniper Elite 3 (set in North Africa during WWII, following Karl Fairburne) works entirely offline and does not trigger such errors.
  • The error appears only when trying to play co-op or multiplayer modes, and the game fails to connect to Rebellion’s servers (or the host’s session).

Common causes for the error in Sniper Elite 3:

  1. Server shutdowns (official multiplayer servers for older titles are sometimes limited or peer-to-peer dependent).
  2. Firewall/antivirus blocking the game’s executable.
  3. Port forwarding issues (UDP 27015–27030 for Steam version).
  4. Corrupted save data or outdated game version.

If you want to focus on the story without connection issues, simply play the campaign offline. The error won’t appear there.

Fix #2: The "Steam Friends" Status Check (PC Only)

SE3 relies on Steam's "Rich Presence."

  • Action: Open Steam. Go to Friends & Chat. Change your status to "Online" (not Away, Invisible, or Offline).
  • Action 2: Go to Steam > Settings > In-Game and ensure the "Steam Overlay" is enabled for SE3. Rebellion used the overlay to broker connections.

Step 3: Check Your Internet Connection

Ensure that your internet connection is stable and fast enough to support online gaming. You can check your internet speed using online tools such as Speedtest.net. If your internet connection is slow or unstable, consider upgrading your plan or contacting your internet service provider for assistance.

5. Try a Different Host or Lobby

If the error appears only when joining a specific friend, ask them to restart their router and relaunch the game. Alternatively, have a different player host the session.

2. Allow Sniper Elite 3 Through Windows Defender Firewall

  • Go to Control Panel → Windows Defender Firewall → Allowed apps.
  • Click Change settings → Allow another app → Browse for SniperElite3.exe (or SE3Launcher.exe).
  • Ensure both Private and Public boxes are checked.

When Nothing Works

Because Sniper Elite 3 no longer receives active updates (its multiplayer community has largely moved to Sniper Elite 4 and 5), some network configurations simply won’t be compatible. Consider these workarounds:

  • Use a virtual LAN tool like Radmin VPN or Hamachi, then set your in‑game network to “LAN” mode.
  • Play the single‑player campaign + DLC (Save Churchill, Hunt the Grey Wolf) — they offer hours of tactical sniping without any connection requirements.

Step 4: Configure Firewall and Antivirus Settings

Firewalls and antivirus software can sometimes block the game's connection to the server. Try temporarily disabling your firewall and antivirus software to see if it resolves the issue. If it does, you can add an exception for the game in your firewall and antivirus settings. No , it’s not a story element

Steam:

  • Steam download region mismatch – Go to Steam → Settings → Downloads → Download Region. Ensure you and your friend are using the same region (e.g., "US - New York").
  • Disable Steam Overlay – Right-click Sniper Elite 3 in Library → Properties → General → Uncheck "Enable Steam Overlay while in-game".
  • Verify game files – Properties → Local Files → Verify integrity of game files.
