MTA:SA error code

MTA:SA error CC30

The server refused the connection.

How to fix it

  1. Try the connection again

    Close MTA, open it again and connect once more. A single failed attempt can come from a restart on the server or a short break in your own connection.

  2. Ask the server, not MTA

    If the message names a server rule, a kick, a ban or a reason, that decision belongs to that server. Take the exact message to the server's own forum or Discord. MTA cannot change another server's decision. On CIT, ask in game with J > Support or /sup, or post the exact message on the General Support / Questions board (cit.gg/index.php?board=15.0).

Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.

About this code

MTA's own client shows a CC code when something fails before or during a connection: the address, the nickname, a module it could not load, or the connection itself. MTA's own documentation gives CC30 as Connection refused.
