Teredo is not working, i cannot install it under device_manager>Legacy_hardware>Microsoft...

I do not have Teredo Adapter under | Devices > Action > Add Legacy Hardware > Next > install manually > network adapters > microsoft > NO TEREDO

If this is any help I've been told to look in device manager for Microsoft teredo tunneling services or something like that and its not in the device manager. So I followed the steps for installing it. I went to Action - Add legacy program - Install hardware
- Network Adapters. But when I get to this point and looked through Microsoft manufacturer I cannot find the Microsoft teredo adapter. If there is another way of installing it please let me know. Also let me know if this would solve my problem.

Thank you for the suggestion, I did find out that "Teredo is unable to qualify" however all the solutions on the "NAT type on Windows displays "Teredo is unable to qualify" Microsoft page did not work, and I still cannot connect to Horizon life, could this be a problem on their end?

None of the solutions works here and it's not a router issue.

Teredo does not exist at all, and is not on install list in Windows 10 in device manager or in hidden devices.

The Teredo Fix button fixes nothing.

100% of PC games not made by Microsoft works perfect online. 100% of Microsoft games is offline because they use Teredo.

I get no error message in Flight Simulator 2020, but i'm 100% sure it hangs at 20% only because of missing Teredo.

And btw. My other PC here have working Teredo on same router, but is too weak to run any game made the last 5 years.

Teredo on this PC doesen't exist at all, and can't even be fixed.

same problem, already reset the xbox app, removed my microsoft account, deactivated proxy, updated all apps, installed all windows updates.

i checked teredo via admin cmd:

netsh interface teredo show state

the output was "state: disabled"

i activated it using:

netsh interface teredo set state client

login still doesn't work
