What it means

MTA downloads a server's resources before you can play, so a nearly full drive stops the connection.

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 Fatal: insufficient disk space.

How to fix it

Work down the list and stop when it is solved.

  1. Free some space on the drive MTA is installed on

    Empty the recycle bin, remove files you do not need, and try again. A few gigabytes of room is a safe target.

  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.

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