Conan Exiles Server Troubleshooting

Mod Mismatch

The #1 connection issue. Client and server must have exact same mods in the same order.

Fix: Ensure players subscribe to all mods and enable them in the correct order. The game shows which mods are missing when joining fails.

After game updates: Mods may be outdated. Wait for mod authors to update, or temporarily remove the broken mod.

BattlEye Errors

"Authentication Failed":

• Reinstall BattlEye from ConanSandbox/Binaries/Win64/BattlEye/ — run as Administrator
• Or disable: IsBattlEyeEnabled=False in ServerSettings.ini (may be needed for some mods)

Server Not in Browser

• Verify ServerQueryPort=27015 in Engine.ini
• Ensure UDP 27015 is forwarded
• Try adding manually via Steam server browser

Connection Timeout

• Check all ports: 7777, 7778 (UDP), 27015 (UDP)
• Verify game files via Steam
• Allow Conan Exiles through Windows Firewall

Performance Issues

• Reduce MaxAggroRange (default 1000) — biggest NPC AI overhead setting
• Lower max players if many large bases exist
• Use NVMe storage for faster database reads
• Monitor during Purge events — they cause CPU spikes
