Disconnect when joining friend

Every time I try to join a friend or him to join me it’s disconnect us and we can’t join it’s been like this for 2 month we are on XBOX ONE.
My gamertag is Betha44 and my friend is BlatteJeje, we both play from France last time we tried it was at 16h29 the 19 august 2017.

Hey OP, this is a known issue that 343 and CA are tracking right now. Unfortunately there isn’t a fix available for it yet
