What it means

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 this code as Connection refused.

How to fix it

Work down the list and stop when it is solved.

1. 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.

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. 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.
