Can't get server list.

I am really frustrated on this one, I tried everything, Verify cache, Change file path, Even re-installed gmod a few times… I don’t get the issue, I COMPLETELY disabled my firewall, And norton it’self for a while, And IT still did not have any affect, I made sure it knew hl2 had all access… I tried everything, Please someone help… If theres something I havent tried yet please tell me, I do not see the issue.

Explain the problem, before explaining what you’ve done to fix it.
I wonder what could be over there

No one knows, nobody has lived to tell the tale…
