Cannot connect to Xbox Live Parties

Hi i cannot connect to a particular friend on xbox live why is that i can only connect through a different persons party with him

There isn't a problem with my Xbox Live connection and my Xbox doesn't warn me about any NAT issues. I don't know why my connection is like this, but when I play I usually have 3-4 connection bars and can play usually without lag. When trying to join my
friend's Xbox Live Party, I get the message popup in the top right "Can't connect to Party" and if I hit the center Xbox button on the controller, the party tab says "Cannot connect to Xbox Live Party. There may be connection issues." I can however, connect
to Xbox Live and play online.

Am also having this issue since the update. Cannot join parties, cannot invite people to party i've started either. Error message, 'can't connect to xbox live party'. Can join game invite and can invite people to game without any issues. Will try the above
when I get home, fingers crossed.

Hi,

Server error is one of the possible reasons why you're unable to connect to the party chat Xbox live on the Xbox app. To help you resolve this issue, we need to gather more details. Kindly answer the questions below:

• Have you tried using a different profile and check if the issue persist?
• Were you able to connect to the party chat before?
• Have you tried uninstalling and reinstalling the Xbox app on your computer?

In the meantime, we recommend that you perform all the troubleshooting steps provided on the links below:
