Find the next useful clue

Start with the symptom. The dashboard's Server Health checks and a world's Logs usually point to the next action.

What you see What to check first
Admin UI unavailable just after an upgrade Allow migrations to finish; inspect container logs if it persists
No worlds after an Unraid move or restart Confirm the original data path is mounted; check the appdata pool
World will not start Open that world's Logs and inspect its latest start or update operation
Player cannot see the world Steam sign-in and the world's Access list
Player sees a mod mismatch World update completed, then client sync completed
Mod is missing from the picker Catalogue filter, sync progress and per-catalogue sync log
Scheduled backups do not run Separate backup volume, free space, schedule and activity requirement
Hugin cannot inspect anything Provider connection and model tool support
Vibes cannot build Build Pak, harvested game libraries and the Build tab diagnostics
Git fetch or push fails Remote URL, token permissions and the branch state in History

A modded world crashes

Try a vanilla test world to check that the host and game work. Then narrow the mod collection. A successful download or compile does not prove that a mod is compatible with the current game or every other mod.

Read the right log

World Activity groups PhValheim operations and their outcomes. Valheim contains the game's log. Both puts them together. The server-wide Logs page can filter by world, source and level.

Ask for help

Discord is a good place for setup help. For a repeatable problem, open an issue with:

  • Your PhValheim version and deployment type.
  • What you expected and what happened instead.
  • The operation's error and the steps that reproduce it.

Remove passwords, API keys, access tokens and private player information before sharing logs or screenshots.
