Server List Not Showing

My Gmod works fine for single player, but when I try to go to multiplayer the server list will not show up and wont refresh either. I have already tried downloading the game and the steam launcher and still nothing seem to work. My internet connection is fine so it wouldn’t be that. Thanks for any help you people give me, it is much appreciated.

go to settings in steam
in-game server browser max pings/min
lower this to 3000

that worked for me
