It doesn't work for me

I made everything good, and when i open TheCOServer and put my IP, i press Listen... It say "Server successfully started."
And than i get in the qonquer client, i put my IP in the server.dat, and when i try to log in the server with the account that i made (With the AccountCreator) its always say-
"Error:Connection with the server is interrupted. Please re-login."
