Avorion Server Troubleshooting

Server Not Listed Publicly

Set isListed = true and useSteam = true in server.ini under [Networking]. Restart the server.

Cannot Connect

• Verify firewall rules for all ports: 27000 (TCP+UDP), 27003 (UDP), 27020 (UDP), 27021 (UDP)
• Direct IP only works on port 27000 — custom ports require Steam networking
• Check that useSteam = true for the best connectivity

Save Corruption

Cause: Force-closing the server console without using /save and /stop.

Prevention: Always shut down gracefully:

/save
/stop

Recovery: If backups are enabled (backups = true), find hourly backups in the galaxy folder or backupsPath.

Memory Issues

• Schedule daily restarts to clear accumulated memory
• Reduce workerThreads to match your CPU core count
• Reduce aliveSectorsPerPlayer from 5 to 3

Mod Problems

• Ensure modconfig.lua has correct Workshop IDs
• Workshop mods auto-update on restart — restart to pull fixes
• If forceEnabling = true, all clients must have matching mods

Config Keeps Resetting

The server overwrites server.ini on startup. Always stop the server before editing. Changes made while running are lost.

Hosting and Playing on Same Machine

Connect via 127.0.0.1:27000 (local IP), not your external IP. This avoids hairpinning issues.
