It comes only up when i host 2 servers on 1 machine, on the same ip and different ports.
help plz

Okay .. which ports do you use when you host the server? Have you sourcetv enabled? Think sourcetv uses the port 27020 by default.
Is not sure. But look, so that the server is not on the same port as sourcetv If so.

When hosting multiple servers, it's recommended to use 10 port interval, if server one uses 27015, server 2 uses 27025 etc.

Also if you have a server running on port 27020, that server MUST start first!
