50088-MW1 Constant Disconnect

[Aladon]

It only says this when i try to join with jsut a single of my friends, and no others. We have both tried a few methods to solve it but it doesn't work. I get this same code constantly and they receive many different kinds of code each time, any have any solutions please?

First thing that comes to mind is did you or ur friend buy the game with regional lock. If yes than you're gonna have to use a vpn or you won't be able to join each other or anyone else for that matter.

Second run game plain without any mods and see if it persists.

If you are both running current update game version without mods and still keep getting errors than it's just god awful MHW online again, there is nothing you can do about it but hope and check after a while did it get fixed. Trust me the wonderful safemade fixes are all placebo that doesn't work, you will end up causing more damage.

Quoting changelog from Capcom a while back:
(Xbox One only) Improved the processing of the retrieval of session information to reduce the incidence of the error code "50088-MW1", which would prevent you from joining online sessions.
