Ty for your reply.
I did try that solution, but since couldn't find on my PS5 a recently played list of other players. Yet, i have just found my server. It was a tedious process of trying a server and noting down its number. I tried in total 101 servers... and at 102nd i finally hit the jackpot.
Anyway if this happens at every update, i must say it looks to me as really bad implemention, forcing a player to write down in which servers he plays.
For my future memory.... 5334 😄
