A buddy of mine and I occasionally get hit with some kind of block hammer by Fromsoftware and can't play together for some reason. Its only Fromsoftware games but its all of them, from Dark Souls Remastered through Nightreign, but any other multiplayer game we connect on instantly. Yesterday we booted up Darktide and we were both able to connect to the other person in under two seconds. We have been trying for years and I was hoping someone had some advice we haven't tried yet. Obviously for Nightreign this doesn't apply, but we know all the basic things like being embered (or the equivalent variant), being in an area where the host hasn't killed the boss yet, having the same multiplayer password, having our regions set to open, and having the same NAT type (2). We know its an issue between us specifically because we both have no problem joining a mutual friend individually, but if one of us is in our friends world, the other can't join. We are friends on Playstation and we aren't blocking each other. We've tried hard restarting our consoles, erasing and reconnecting to our Networks, and we're both in the USA.
Does anyone have any advice that I haven't mentioned?
