MTA:SA error code
MTA:SA error CD09
The connection to the server was lost.
How to fix it
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.
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.
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
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 CD09 as Server connection lost.
