Hello friends . Please help me with this problem.

I still connect normally to the teamspeak3 server via serverquery login. But yesterday, when it was working, suddenly my game server was shut down by a hacker. It causes sudden shutdown. Then I reconnected between my game and teamspeak via serverquery login so I received no signal. In my server log there is no sign of the server connected and there is no error message. This is how please give me a solution. I searched through the web but did not know my current status. Hope you all will help me. Thank you, thank you very much
