The Isle Evrima Server Update and Version Mismatch Fix
When Evrima updates, a client can finish downloading before the dedicated server does. The result is usually a missing server, a failed join, or a connection that worked yesterday and times out today. Treat the update as a coordinated maintenance window, not as a reinstall.
Update the correct Steam branch
steamcmd +force_install_dir /srv/theisle \
+login anonymous \
+app_update 412680 -beta evrima validate \
+quitThe -beta evrima selector matters. Running app_update 412680 without the branch can leave a self-hosted install on a different content stream than the players. Never “fix” a mismatch by moving the community to Legacy unless that is an explicit, separate server plan.
Safe patch-day sequence
- Announce a short maintenance window and stop new joins.
- Take a backup of the entire
TheIsle/Saved/directory. - Stop the server cleanly before SteamCMD changes its binaries.
- Run the Evrima update with
validate. - Start the server and wait for EOS registration and listening messages.
- Join with a fully updated Evrima client before reopening the community.
Do not confuse these outcomes
| Observation | Meaning |
|---|---|
| Server disappears during maintenance | Expected while the process is stopped or re-registering. |
| Client says version mismatch | One side has not completed the same branch update. |
| Server starts but nobody sees it | Check branch, EOS registration, filters and ports; it may not be a SteamCMD failure. |
| Progression is missing after a reinstall | Likely a save/backup mistake; use save recovery steps. |
Managed hosting: Supercraft applies the server-side branch update and takes a backup before maintenance. Players still need to restart Steam and finish the Evrima client update.
