When using mumble 1.2.5 and trying to connect to both mumble.tf2center.com and 198.100.150.24 (manually) with the port 64738 I get the messages:
[8:30:27 PM] Connecting to server mumble.tf2center.com.
[8:30:57 PM] Server connection failed: Connection timed out.
This also happens when I click on the "Join Mumble" button on the lobby page (with either mumble already open or mumble not open)
I have un-installed and re-installed both mumble 1.2.5 and mumble 1.2.4 repeatedly--rebooting between each one, of course--and keep getting this error. I am able to join other public servers by going to Server->Connect->selecting any public server (both 1.2.5 and 1.2.4 servers)->Connect.
I would very much like this to be fixed so I can play on mumble required servers.
PS. I am currently using mumble 1.2.5 and Google Crome on a Windows 7 64bit. Here is a tracert if it helps:
