Finding the server
- Most reliable: in Valheim Join game → Join IP → enter the address with port (top of your server page).
- The server only appears in the community list if Public server (
PUBLIC_SERVER) is on – and only a few minutes after starting. - If crossplay is on, everyone joins via the join code – see Crossplay.
"Wrong password" or server doesn't start
Valheim has strict rules for the server password:
- at least 5 characters,
- it must not appear in the server name.
Otherwise the server doesn't start or rejects everyone. Change the password in the Startup variables tab and restart.
"Incompatible version"
Almost always right after a Valheim update: the game is newer than the server. Restart the server – with Automatic updates on it downloads the update itself on start.
If you deliberately play a beta (beta branch in the startup variables), all players have to pick the same beta branch in Steam.
Mod server (BepInEx or Valheim Plus)
- All players need the same mods in the same version as the server. Easiest with r2modman or the Thunderstore Mod Manager and a shared profile code – see Install Valheim mods.
- After a Valheim update some mods may not work for a short time until their author updates them.
The world is suddenly empty
The server loads the world named under World name (WORLD). If the name doesn't match, it creates a new world. Check the name – your old world isn't gone, it just isn't loaded.
