WHY CANT I CONNECT TO ANY SERVERS

I've tried every game mode and every damn region and it still says failed to connect no matter what and I tried to join servers on other games too but it's not letting me. And I can't get anywhere with steam support so

@ihatesupport Have you tried to join a community server using appropriately named Community Server section of Server Browser ?

Matchmaker may have its own issue however if you cannot connect to custom servers which uses direct connect then the issue is likely that your ports and network is being blocked.
