3. Connect again, then compare with another server

   Connect again. If the error is still there, try another server you trust to compare. Then report the exact protocol message and the MTA build you have installed. Do not change your account password or your serial to try to fix a protocol mismatch.

These are the steps of the guide Disconnected by an unknown protocol error.

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 CD10 as Encryption/protocol mismatch.
