Make sure that you and your friend are on the same game update version. For example, if your friend is on version 1.0 and you’re on version 1.2, you won’t be able to connect. You should also make sure that the two have you have a stable internet connection (vastly different/fluctuating ping will lead to disconnections)
Lastly, make sure that neither of you have any cheat codes activated or used save states prior to connecting.

Hi, afterwards I also tried this with my two computers on same local network (citra room on wan ofcourse) same upd. version, no cheats already, stable very low ping internet connection. Still same issue. Also tried with mk7 still same issue.

MK7 specifically is a title that required DLP files in order to use the local multiplayer features. What was the first game you tried?

first was tekken 3d prime
