# Game Server Troubleshooting

> Diagnose and fix common issues on CrazyNode game servers.

Most game server issues fall into a handful of categories. Work through this list before opening a ticket.

## Server won't start

1. Check the **console** for the exact error message.
2. Recent config change? Revert `server.properties` / `server.cfg`.
3. Recently installed a plugin/mod? Remove it and retry.
4. Confirm the correct **startup jar** is set under **Startup**.
5. Check disk usage — a full disk prevents startup.

## Can't connect to the server

* Verify the **IP and port** shown in the panel.
* Confirm the server status is **Running**.
* Test connectivity: `ping YOUR_IP` from your machine.
* Check your client version matches the server version.
* For Minecraft: `online-mode=true` requires a legitimate Mojang account.

## Server is lagging

See the full [performance guide](/game-hosting/performance). Quick wins:

* Restart the server
* Lower `view-distance` (Minecraft)
* Remove heavy plugins / resources
* Pre-generate chunks

## Crashes or freezes

1. Read the console output at the moment of crash.
2. Look for **stack traces** naming a specific plugin or mod.
3. Update or remove the offending content.
4. If out-of-memory, request more RAM via [upgrades](/billing/upgrades).

## Lost world / corrupted files

1. Stop the server immediately.
2. Restore the most recent [backup](/game-hosting/backups).
3. Investigate root cause (crash, plugin, disk issue).

## Still stuck?
