Xbox Party Issue, can’t connect to specific friend

Xbox Party Issue, can’t connect to specific friend
I have contacted Xbox support nearly a hundred times to try to resolve this and there is just no fixing it. For the past few months out of no where I can’t connect to a party that a specific friend of mine is in. I have tried everything that Xbox support
can think of and it won’t work. Whenever I try to join a party that he is in I end up disconnecting before even connecting. I have no clue on how to fix this abs it only happens between us and occasionally one other. It occasionally works for maybe a feeble
day and then stops working for a few weeks. Please help

:)

 

Friends muted

When I join a party some of my friends are muted and I can’t unmute them, I tried hard resetting my Xbox I tried unmuteing them on there profile but nothing worked. I don’t know if this is an issue with Xbox live or not. I think it is because my friends
also have this issue one of my friends has me muted and they can’t unmute me please help.

 

Social and gaming problem

So I just got back home from a friends house with my xbox one x working perfectly fine no issues with connecting to parties or even accessing games before I left. Hooked it up at my place can’t connect to a party nor can I connect to any multiplayer game,
is it just an xbox one x issue because I have reset my internet several times and the internet works fine I can connect the xbox to it but I’m not allowed to connect to anything and yes I do have xbox live gold, and have not been coms banned
