I've had a mumble server up that was previously scannable by GameTracker, but has sometime in the past couple weeks become unscannable.

The IP and firewall information have not changed on my end.

Dude Dont try as soon as you open the server try to scan It after sometime. And If it still do'nt work then go to the port forward delete everything and again do the port forwarding/. Then go to the gametracker delete the server and then add it again server will up definately. But as soon as you do these please do not forget to claim your server and then you know how to claim it right if you do not tell me I will tell you
