Failed to Join session / Nat type unavailable

[(XBOX)Dex Xean]

I have been having issues playing with clanmates and friends in a squad lately and went to check my network settings and it said Nat was unavailable check your teredo. Then to find out teredo was unable to qualify. So I went off to xbox website to try all their solutions which does not work then I went to Reddit and microsoft forums and here to see if any1 else was having problems and it seems Peer to Peer games on xbox are having this issue pop up cause Borderland 3 players are also having this problem. Im just curious if any1 else might be running into this.

Also various threads in this xbox matchmaking bug forums.

 

 

Edit: biggest reason I care so much about this is well I would like to play with my friends cause atm due to this bug Im literally a solo player when Railjack is on the horizon for PC. so I have until Consoles get railjack for this to be fixed hopefully b4 it drops. I can still play solo ofc but would really nuke my experience when I actually have a clan/alliance and friend to do railjack with. I can still sometimes connect to other players but it looks like they literally will either d/c or for a small amount of time I can play fine but then they all drop and I run into the fail to connect to session error.

Edit 2: Found another thread on xbox help forums with this issue.

I was having the exact same issue. Anything using peer to peer connection would not work but anything using a server works like nothing's wrong.

I say "was" because suddenly my NAT is back to open. Didn't do anything other than mess around on Crossout, uses servers in matches, for a few hours. Hopefully this is a sign that it's being fixed, but the lack of official word other than something about xbox live messages not working is strange.

I experienced the same thing, and it still hasn't been solved yet. I tried everything what I could find to solve this problem, but I couldn't achieve anything. :(
