Random Co-Op Disconnects in Rivals

When me (PC) and my friend (PS5) wants to play co-op rivals. We can only play home games, if we play away games we get disconnected after a couple seconds with the message: You have forfeited the match because of not enough players. We have the same issue for a couple of weeks now. Please fix it i paid almost 5 thousand euros in this game and i cant even play with my friend. This is not normal...
