Unable to join friends world

I wasnt able to join their worlds and they were unable to join mine. Im not sure if it applies, but I also had a thing where both me and one of my friends skins changed to be the exact same and now I am unable to change my skin at all. But im not too fussed
about that. I simply want to be able to join my friends world.

Hello, whenever I try to join a friends server it says unable to connect to world and if the try to join me they get hit with the same message.

This happened to us yesterday. I left the game and when I wanted to join again 5 minutes later I got the message 'Unable to connect to world.'. My friend was hosting her world on Xbox One with Minecraft v1.12.0, and I have the same version. Another friend
was also playing in that world from his pc and he didn't have any problems. Everything seemed fine besides that I couldn't join anymore. So then another friend tried to join as test but she couldn't join them either. We did some further testing and I could
join that last friend's world and she could join mine, and I could join the world of yet another friend, but no one was able to join the game I left.

The friend hosting the game didn't do anything besides playing the game. I had left a few times before and could always join again.

I wish the game would give more information beyond 'Unable to connect to world.'.

I cannot join my friend's world (we are both ps4). We are both NAT type open and i've tried everything to join, it keeps saying unable to connect to world and i desperately need to play. Thanks, I appreciate
any help

Make sure the world is set to allow friends to join and not single player amd your both on the same verson
