Cant find a match

The same thing is happening to me, my friends keep saying "Oh you must have a bad connection", but I have a high speed wired connection there's no way that's the problem and when I join a game in session there's no lag at all, but when I search for a match,
alone or in a party with friends, my Xbox freezes and it kicks me back to the main menu. When I played earlier in the afternoon it didn't happen at all I could connect just fine.

i always have problems when we have a team of 6 it will never find a match......

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today buddy

Please answer the following questions:

Is this happening with both games?
Did you try using another Wi-Fi network?
Do you have cross play enabled ?

I’ll be waiting for your feedback, cheers from another Microsoft user!

I've had no problems finding a game, ever.

The same here. My NAT was moderated - so i changet the ports. Now the Nat is OPEN - but i still cant join when im playing 1. If whe are in party - after like 10mins somebody of us 5guys can manage to find a proper game - and then we just play there no metter
