Nioh 2 multiplayer set up and strange question……

Playing on pc with steam , then using my steam deck but with a new and different account that has its own nioh 2 game in its account also from steam. So it should be like I have two devices with two copies of the game. I am friends with the new account but it’s not part of a family plan or anything.

I can not for the life on me get the online coop to work for the two devices, on pc can play with other randoms, with steam deck same thing can play with randoms but when trying to make a private match with password, not able to find the other account tried using each system to set up, tried using no password but not able to get it.

So a few thoughts and throwing out a Hail Mary if anyone has ever ran into this… so here we go….

We are on the same network, epic game store is disabled on both devices per ingame Nioh2 setting , but I am baffled as to why not able to get this to work ? I have tried as many set up tweaks as I can find out YouTube. But makes me wonder if it’s because of the deck set up where my account is on the deck and game is loaded on steam deck through my normal account , but when I switch accounts using the switch change accounts to the new account ( and not on a family plan or part of one) then it lets me use the already downloaded game from my account ( without my save data from pc, but has its own separate save for the new account)

Just trying to have two devices so we can play Nioh2 together in some online co op. Should work but having difficulties making automatic match with password as it won’t find the other as I have it set up like multiple videos have said to.

Also sorry prob better way to ask this strange question but I did warn you peeps in the title about it.
