We're on pc the thing is he's in Russia I'm in NA. He's also got red NAT though I do have green NAT. We can't connect no matter how many times we try to invite to group. Why's that?
his net isn't that bad either. We can co op just fine in darksouls 3
Can you check and see if you or he can connect when someone else invites you both? Do either of you have trouble when being invited individually by another player?
While NAT issues are less important now that dedicated servers were added, they can still cause issues in PvAI games.
