my friend can not join my world and i can not join his world

I can only join my friends world when he invites me to his workd, but their world does not pop up when I go on the friends tab. They also have their world on friends only and he already has me added as a friend. All my other friends can join his world
except for me. The only way I can join is if they invite me. I need help with this pls

I can join his worlds and my nat type also open its just he cant join my worlds

firstly check the game settings then check your privacy settings could be a issue with friends that have not added you as a friend not allowing them to join lastly check nat type settings and ask your friends to do the same.

Thank you for the reply.

My settings allow friends and friend of friends to connect.

As i said, when nobody is connected on my world, one person only can join.

Let me explain with an example :

I am in my world

Friend A tries to join my world : success

Friend B tries to join : failure.

Friend A disconnect himself

Friend B ties to join my world : success

Then, Friend A tries to join again : failure.

The problem is that only one person can join me, and nobody else can, no matter who it is.

Hi Amanda!

Sorry to hear about the issue. Just to confirm, is she the one who can't join your world or you are the one who can't join her world?

I know your other friends can join your world but are her other friends able to join her world as well except you?

Hi, there is no error code for people trying to join my worlds and we all have the same updates and betas when we try joining my world, however i can join their worlds just fine
