Managing your Valheim server
Updated July 03, 2026
Valheim Valheim Maintenance
Backups, scheduled restarts, and troubleshooting for a long-running Valheim server.
Scheduled Restarts
A daily restart keeps memory use in check. From the Schedules tab:
- Create a schedule named "Daily Restart".
- Cron:
0 5 * * *(5 AM server time, adjust to your quietest hour). - Add task: Send Power Action, Restart.
Backups
The world files in worlds_local/ are small (a few MB to a few hundred MB). Snapshot daily through the Backups tab. Always back up before installing or updating mods, because a bad mod can corrupt the world.
Common Issues
- Cannot connect: Almost always the password. Valheim requires at least 5 characters; empty passwords are rejected on public servers.
- Mods will not load: Check
BepInEx/LogOutput.logfor compile errors or missing dependencies. Most mods need the BepInExPack, which thebepinexserver type installs by default. - World corrupted: Restore the
.dband.fwlfiles from the most recent backup. - Server crashes after a mod update: Roll back to the prior mod version. Valheim mods occasionally break across game updates; Thunderstore tracks compatible versions.
