Managing your 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.

A bad mod can corrupt the world

Always back up before installing or updating mods, because a bad mod can corrupt the world. See taking and restoring a panel snapshot.

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.
