Download blocked with double NAT on Series S

My question is, can microsoft confirm that it blocks game downloads on double NAT & NAT Type strict?

I tried connecting my mobile Hotspot with NAT open and single NAT, game download resumes. But I cannot use mobile Hotspot to download as it's quite slow.

For testing, I tried routing Xbox network traffic over VPN via my laptop and downloads were working fine. I have not reset my console yet, still doesn't explain what's blocking the download.

If reset was the culprit it shouldn't have worked over VPN either...

Funny thing is, over VPN NAT is moderate, UPnP unsuccessful yet downloads works and direct network connection NAT open doesn't work... 😂

Hi, thanks for the info. I have tried those steps multiple times and is a frequently suggested steps to perform. But this has not solved the issue.

What's next? I am unable download games on my new series s even though I have paid for Xbox ultimate pass...

Worked with my ISP to unblock all ports. And I have personally verified all the ports listed on Xbox support.

But download still stalls after roughly 10 GB.

Now I strongly believe something is definitely wrong with Xbox software. Any way to get the system logs to verify...

Yes. I have notified my ISP about this finding. As a computer engineer, I am curious about the root cause. Any ideas or checks that I can try?

I worked with my ISP to resolve Double NAT and setup port forwarding. Now, on my Xbox series s, it shows NAT Type open, all the tests are successful, does not show any issues.

Question now remains, why does not the download happen?. Before you suggest power cycles and restarts, already tried those. No luck.
