Party glitch

One thing you should check is whether your ISP bumps everyone at a certain time to get rid of active but unused connections. If it happens at the same time every day that would likely be the cause

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Please perform an extended powercycle and reset your network hardware by following the steps below:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.

Im having the same issue. Ive tried everything:

Quick resets

Tried blocking and unblocking (since it tells me they are blocked)

Tried muting and unmuting

Tried deleting and readding as a friend.

WiFi deletes and reconnects

Hard resets

And factory resets.

This problem still persists.

I did have it work on 1 friend. But now it's gone to another one.

We both were trying all of the things above. Just to get one friend in our 3 person party. Now it's on to friend #2

Maybe a glitch. One time it let me into my friends party uninvited.

Fortnite and the Party Chat are the only known issues right now, I’ve uninstalled and reinstalled multiple times, I even did full restarts on my Xbox and no luck at all, I use Wireless Internet.
