University Wifi & Voice Chat

About a week ago I stopped being able to join any voice chat (group or team) in overwatch (but only overwatch). I try to join and it never does (the sound and message saying you joined doesn’t even come up) so I cant hear anyone and they can’t hear me.
I tried connecting with my phone’s mobile data and it worked so I suppose it has to do with the Uni Wifi (it being the only connection I can use). Any tips on how to fix this issue? (All other games and apps work just fine)

The Blizzard staff has a possible solution/next steps in the pinned threads:
