(Locating server) I just can't join any of my friends

Since a few months, I can't join any of my friends. I can join on my own worlds but when I try to join them it's stuck on "locating server". The game doesn't crash, I can leave the loading screen but I just don't join. I already deinstalled every data of MC but nothing changed. I'm playing on my PS4 on MC Bedrock.

It would be very nice if anybody could help my with my problem. I didn't find any of these problems here yet.
