Short answer

What do I do if the FS25 server won't start after an update?

First steps: stop the server completely and restart it. Check the web interface for an available manual update. Check the server log for error messages. Disable all mods and test whether the server starts without them.

Nothing works after the update

Giants Software regularly releases updates for FS25. After some updates, servers won't start anymore, players can't join or the server hangs while loading. That's frustrating — especially when you didn't change anything and it worked fine before.

Basic rule after every update: Server software and game client must always be on the same version. If either of them is outdated, connection problems are the result.

Immediate steps after an FS25 update

1

Restart the server

Sounds trivial — but many providers apply updates automatically when the server is restarted. In the web interface: stop the server → wait until it has fully stopped → start it again.

2

Trigger the update manually

Some providers have an "Update" button in the web interface. Click it and wait until the new version is installed.

3

Check the server log

In the web interface → Logs → look at the latest entries. If you see a line like "Version mismatch" or "wrong version", the server version is outdated.

4

Check mods after the update

Sometimes updates make mods incompatible. Disable all mods, start the server, test. If it works then: re-enable mods one by one until you find the culprit.

Restore a backup if nothing else helps

If the savegame is corrupted after an update (recognizable by LUA errors in the log), restoring a backup helps:

  • In the web interface → Backups → choose the last backup from before the update
  • Restore it and restart the server
  • Caution: progress made after the backup was taken is lost

That's why regular backups are a must. Check whether your provider creates backups automatically, and also download the savegame directory via FTP before major updates.

If the server stays down after an update

After an update, it can take a while until your provider's support replies. To get your request handled quickly, include the key information right away: the server log, the time the problem started and your latest changes (e.g. new or updated mods). Until then, you can work through the immediate steps above yourself or restore a backup from before the update.
