Players can't connect	Ensure game version matches between server and clients. Check server password
Server crashes on start	Check Console for error messages. Check Console for error messages
Mods causing crashes	Remove recently added mods from `Content/Paks/` and test. See Mod Setup
Save not loading	Verify the world folder exists in `AbioticFactor/Saved/SaveGames/Server/Worlds/`. Check file permissions
High latency / lag	Reduce max players. Check server RAM usage in Console stats
Config changes not applying	Stop the server before editing. The server may overwrite configs on shutdown

Open Console in the XGamingServer Panel and look for Error or Warning messages at startup. The first error is usually the root cause.
