Here's how to connect to your Valheim (Mods / BepInEx) server and adjust the most important settings.

Connecting

  1. Open the server page in the client area and click Start.
  2. Wait until the status shows “running”. You can follow the progress in the Console tab.
  3. Copy the address (IP:Port) at the top of the server page.
  4. Launch Valheim and choose Start game → Join game → Join IP – enter the address there.

Important settings

In the Startup variables tab:

  • Backup Count (BACKUP_COUNT) – Sets how many automatic backups will be kept. The first is the 'short' backup length, and the rest are the 'long' backup length. When default values are used means one backup that is 2 hours old, and 3 backups that are 1.
  • Backup Interval (BACKUP_INTERVAL) – Change how often the world will save in seconds. Default: 1800 (30 minutes).
  • Backup Longtime (BACKUP_LONGTIME) – Sets the interval between the subsequent automatic backups in seconds. Default: 43200 (12 hours).
  • Backup Shorttime (BACKUP_SHORTTIME) – Sets the interval between the first automatic backups in seconds. Default: 7200 (2 hours).
  • Enable Crossplay (ENABLE_CROSSPLAY) – Enable crossplay support.
  • Server Password (PASSWORD) – Server password.
  • Public Server (PUBLIC_SERVER)

Changes in the Startup variables tab take effect on the next restart.

Good to know

  • Put mods (BepInEx) into BepInEx/plugins in the Files tab; players usually need the same mods.
  • The first start takes longer because the server files are downloaded and set up.
