Have you tried to reset your filters? Or it could be issues with your connection.

it probably not my connection cause everything working and how do i reset my filters?

In the Legacy Browser, you should have a filter button. You can reset the filters there. Or try joining using the Legacy Browser.

what is legacy browser and how do i get to it?

When you select, Find Multiplayer Game, the last option is Legacy Browser.

Im having the same exact problem. Is this what you see?

yes exactly

Your firewalls are blocking GMod from accessing Internet.

im actually shocked that the didnt even check to see if that is blocking it. Usually steam states that your firewall is blocking that game(s)
