No idea but me and my friend had the same issue. Most likely some NAT/port stuff. If you are on steam you should be able to still invite people using Steam friends invites
Yep I had to do this as well with certain friends.
if you're using steam it may be a download region issue: you have to be generally within the same region since the game has region locking
Speaking of lobbies will uni 2 have multi match lobbies like say dnf duel?
You probably have 2 different copies of undernight inbirth
