Game Server Troubleshooting

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. 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.

​

Lost world / corrupted files

1. Stop the server immediately.
2. Restore the most recent backup.
3. Investigate root cause (crash, plugin, disk issue).
