Joining multiplayer games.

Hello I am having issues with joining multiplayer sessions in a few different games and with making calls on Discord.

My internet is is working fine for browsing watching videos, streams but every time I try to join a game with other players I cannot join their session or it gets disconnected. [Helldivers 2 / Deep Rock Galactic] I can use chat to communicate with people but when I added them to friends group they report not even seeing me as online. That same thing might be causing an error every time I try to join or start a Discord call [stuck in "Connecting" or "RTC route"] the same happens when I try to stream.

I use Windows 10.

Tried reinstalling all programs that encounter this issue, flushing dns, resetting my router, checked specific program servers for being online and not reporting any connectivity issues.
