server.log.txt (and server.crash.txt after a crash) in .local/share/Euro Truck Simulator 2 in Files. The most common cause is a missing or broken server_packages file. If settings change back after a restart, you edited a key the panel writes from Startup (lobby_name, max_players, ports, server_logon_token); change those on Startup instead.
Server won’t start
How to find the error
1
Watch the console
Start the server and watch the console. A healthy start ends with
[MP] Session running..2
Open the log
In Files, open
.local > share > Euro Truck Simulator 2 and open server.log.txt. Read the last lines. After a crash, also open server.crash.txt if it exists. See server logs.3
Undo the last change
Most failures follow a change. Put back the previous
server_packages or server_config.sii, or restore a backup.4
Still stuck?
Open a ticket and include the last lines of
server.log.txt.Settings change back after a restart
The panel writes these keys intoserver_config.sii every time the server starts:
Every other key (
password, description, welcome_message, moderator_list, traffic and the rest) stays as you saved it.
Max players goes back to 8
That’s the game’s limit. SCS caps a dedicated server at 8 players, so a higher Max Players value is reset to 8 at start. See max players.My Startup change did nothing
Startup values apply at the next start. Click out of the field so it saves, then restart.Frequently asked questions
