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:

  1. Create a schedule named "Daily Restart".
  2. Cron: 0 5 * * * (5 AM server time, adjust to your quietest hour).
  3. 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.log for compile errors or missing dependencies. Most mods need the BepInExPack, which the bepinex server type installs by default.
  • World corrupted: Restore the .db and .fwl files 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.
  • Server Configuration for world management and the wipe procedure
  • Mods for the BepInEx setup that most of these issues relate to
