How to Fix ETS2 Version Mismatch & Downgrade Your Game

The most common connection issue with ETS2 servers is a version mismatch — the game client updated but the dedicated server hasn't yet.

Why This Happens

• Steam auto-updates the game client immediately
• The dedicated server update via SteamCMD can lag behind by several days
• Both must be on the exact same version to connect

Fix 1: Downgrade Your Game Client

1. In Steam, right-click Euro Truck Simulator 2 → Properties
2. Go to the Betas tab
3. Select a temporary_X_XX compatibility branch from the dropdown
4. Steam will download the older version
5. You can now connect to the server

Fix 2: Update the Server

If a server update is available:

1. Stop your server
2. On the Dashboard in the XGamingServer Panel, click Reinstall Server
3. Wait for the update
4. Start your server

Prevention

Disable automatic game updates in Steam to avoid surprise version mismatches:

• Right-click ETS2 → Properties → Updates → Set to "Only update this game when I launch it"

💡 Tip: Check the SCS Software blog or forums when a new update drops — if the server update isn't out yet, downgrade your client temporarily.
