Question

Xbox NAT type won't show anything but Unavailable. Keeps giving error messages

Trippen 40

Having the same issue. Tried everything. Was on the phone with Xfinity for 2 hours trying to trouble shoot everything to get my NAT type to show anything other than unavailable. Everything was working fine up until 2 weeks ago when this started to happen. Followed all troubleshooting steps for Tespo or whatever it is as well as UPD 3544. According to reddit and a problem across the entire country with all internet providers. This is a MICROSOFT issue 1000% and they need to address this now.

UDP port 3544 for Teredo is what I meant. Also did everything for Firewall setting to add a new rule to allow this.

Having same problem with a different ISP provider. Troubleshooting was discovered that XBOx is running on windows 10 not 11.

I downloaded a free copy of Ghost Recon Breakpoint on my Sony PlayStation 5 today. That is the game I have been having the most issues with on Xbox. Haven’t been able to play it online with a buddy for 3 weeks+. I launched the game, went into the peer to peer lobby and co-op fired right up, no problems. No issues with Teredo, NAT type, DMZ, port forwardig, QoS tagging…nothing. That tells me the online issues we are all having isn’t the router, the provider, in my case it isn’t even Ubisoft. The issue lies with Microsoft. Something happened after the update back on 12/5 that is causing the issue. I emailed “Rafael” with Xbox support. I’m sure a crack team of engineers is about to have a break through any minute now. In the meantime, Microsoft continues to take money for games/services they don’t work as advertised. Buyer beware.

Bret Conti…don’t know if you’ll see this comment but I feel your pain. They deleted your comment because you used a curse word. This has been going on for a month. Microsoft knows it’s a problem but is more concerned about appearances and hiding it than fixing it. Good luck.

Here is my open ticket number with Microsoft and the ongoing issues with NAT being unavailable for the past four weeks: 7093308506

Hi Trippen,
Welcome to Microsoft Q&A forum. I'm happy to help.

This problem typically does not originate from Microsoft. Instead, it's caused by factors outside Microsoft's control.

Your Router
- UPnP is disabled.
- Router firewall or filter rules.
- Multiple NAT: your connections go through multiple routers before reaching WAN.
Your ISP
- Blocked in ISP-level firewall.
- You're in CGNAT (Carrier-Grade NAT) zone.

Carrier-Grade NAT (CGNAT) is a technique used by ISPs to conserve IPv4 addresses. Instead of assigning each customer a unique public IP, the ISP places multiple customers behind a single shared public IP. Your home router then uses private IP addresses behind this shared IP, creating two layers of NAT. CGNAT is particularly problematic because even if you configure your router correctly, the ISP-level NAT prevents Xbox from establishing the necessary peer-to-peer connections. In short, resolving this requires changes on your ISP—not Microsoft intervention.

I hope that above information is helpful to you.

Yeah, Im having the exact same issue for about 2 weeks now. Talked to my isp for an hour, enabled uPnP, port forwarded and nothing has worked. Im picking up a new router tomorrow but after reading in here I don't think thats the issue. The last 2 years I've had the same modem, router and ethernet cable and my nat was always open.

The odds of people having the exact same problem from all over the country at the exact same time and it being their fault doesn't seem very likely. I'll contact my isp again tomorrow to ask about CGnat i guess.

This issue did not originate from any settings on our end as I have checked every possible approach there is to solving it. At this point it's clear that it was because of the Xbox system update.

This is an Xbox problem. I know multiple people this is happening to.

Thanks for taking the time to respond but this isn’t a router or provider issue. This is occurring in different cities, with different providers, with different games. It wasn’t an issue until the last update.

I’m able to play the exact same game on PS5, online, peer to peer without any trouble. There are multiple people reporting this issue via Reddit, Down Detector, Facebook and X. Everyone from Microsoft keeps trotting out the same advice that worked 5 years ago. Clearly something happened on Microsoft’s end 3-4 weeks ago.
