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 Expired version.

How to fix it

Work down the list and stop when it is solved.

  1. 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.

  2. 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.

  3. Copy the whole message first

    Write down every line MTA shows, not only the code. The rest of the message often names the file, the server or the reason, and that is what tells you which step below applies.

  4. Check your log if it keeps happening

    Paste the message, or MTA's core.log, into the Fix tool on this site. It runs on your own computer and points at the matching steps.

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