If your Assetto Corsa server isn’t showing in the online list, open the Game Panel console and look for CONNECTED TO LOBBY. If it isn’t there, check that REGISTER_TO_LOBBY=1 in cfg/server_cfg.ini and that the server started without errors. If the server is listed but players can’t join, they are usually missing the track or cars, have a different version of them, or need a newer CSP.

Quick checks

​
How to read the console

Open the console after a start. A healthy start shows, in this order: If the server stops before these lines, the last lines usually name the problem, for example a track or car folder it can’t find. Check that TRACK, CONFIG_TRACK and CARS match folder names in content/tracks/ and content/cars/ exactly, and that MAX_CLIENTS is not higher than the track’s number of pits.

How to fix a server that isn’t listed

1

Check REGISTER_TO_LOBBY

Stop the server, open cfg/server_cfg.ini in Files and make sure REGISTER_TO_LOBBY=1.
2

Undo recent changes

If you just edited the config or uploaded content, check those lines first. Restore a backup if you can’t find the mistake.
3

Start and watch the console

Start the server and wait for CONNECTED TO LOBBY.
4

Search by name

In Content Manager’s online list or the game’s own list, search for your server’s exact name. The list is long, so searching is faster than scrolling.

Why players can’t join a listed server

​
Frequently asked questions

​
Why is my server called AC_Server?

That is the default NAME. Change it in cfg/server_cfg.ini and restart.

​
Can I change the server’s ports to fix connection problems?

No. The panel writes the game and HTTP ports into server_cfg.ini at every start. If you think a port is the problem, open a ticket.

​
The server was listed yesterday. Why not now?

Check that it is still running and that Auto Update (1) hasn’t left players on an older game version than the server. Players should update Assetto Corsa through Steam.

​
Is my server under attack?

If it lags or drops for everyone, see DDoS filters or contact support.
