Garry's Mod not loading servers

Whenever I log onto gmod the servers load. If i wait 30 seconds and refresh the won’t load or will all say 0 servers, 0 players. If I do log on to a server it say connection problems for 20 seconds at a time for the whole time i am on a server. My firewall is not an issue and neither is antivirus.

That’s happened to me before. Just restart gmod and it will be fine. I don’t know any other way though. :pwn:
