Cant join any Steam/Ubisoft Connect friends game

[Botilov]

Hey guys i did a fresh install of windows a few months back and since then i haven't been able to join any of my friends via steam or steam invite.

Public servers i'm able to join.

Some games like Rainbow and some call of dutys even refuse to let me connect to their servers or if im even able get into the game im not able to join any of my friends, even if i send them invites or host the game. 

My network is stable i don't get any network spikes my dns is the google dns.

Pls if you can help pls share the info as i don't want to do a fresh install of windows again and download gbs worth of games!
