The sulution to that problem is faking the clients, Example:
If you were to load these addresses in cheat engine or any other debugger
and join the server and choose a class, then lock in the values to each address and leave. It will trick the server into thinking that there is still someone playing on your server. At first the server will still be empty, But if you were to try to join again with the values locked in it you will get a message "Server connection timed out".
Check the server again and poof there's a fake client playing on your server.
