What it means

A CD code appears when a connection to a server fails, is refused, or ends. Most of them carry a second line with the server's own reason. MTA's own documentation gives this code as Connection desynchronization; details.

How to fix it

Work down the list and stop when it is solved.

  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. Check your own connection

    Open a web page on the same computer. If other things are also failing, fix the connection first. A working website does not prove a game server is reachable, but a broken one explains a lot.

  3. Install the current MTA update

    Close MTA and run the current installer from multitheftauto.com. Several connection codes are simply an old client meeting a newer server.

Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
