Server browsers (steam,gmod) won't show all servers, just fraction of it.

So this started like yesterday, that I can’t get servers to display properly in either server browser, those servers I have in favorite actually display but when I use the legacy server browser or the normal one in gmod or outside in steam it won’t display more then 300 servers.

How am I supposed to fix this issue? I already tried disabling DMZ but it is already disabled in my router, plus I tried resetting firewall rules in my BitDefender, but it just not works at all.

Any ideas?

Ah, okay, was getting worried something is wrong on my PC, lol.

So this is a global issue now? That’s why servers are so empty.
