Windows 10: "Teredo is unable to qualify" in Windows 10 for Xbox App

As the title suggests, teredo is acting up again. I have had this issue more times than I can count now, however this time my previous fixes aren't working. I am on the newest update to Windows 10 (1903) and I have tried everything. I am completely stuck and I really need help. Thanks.

Xbox app on PC - "Teredo is unable to qualify"

Hello,

The problem I am having is that the Xbox app on Windows 10 shows the NAT Type as :Teredo is unable to qualify.

However the problem actually seems to be a disconnect between Teredo and the app, as shown below:

Type : natawareclient

Server Name : win10.ipv6.microsoft.com

Client Refresh Interval : 20 seconds

Client Port : unspecified

State : qualified

Client Type : teredo host-specific relay

Network : unmanaged

NAT : cone

NAT Special Behaviour : UPNP: Yes, PortPreserving: Yes

Local Mapping : 192.168.1.XXX:56398

External NAT Mapping : XXX.XX.XX.XXX:56398

Numbers changed for security reasons

Xbox App network status

Internet Connection : Connected

Xbox Live Services : Up and running

Xbox Multiplayer:

NAT type :Teredo is unable to qualify

Server connectivity : Blocked

Performance:

Latency :Not available

Packet Loss : Blocked

I have already completed all the recommended steps from the following two links:

Teredo unable to qualify

Hi JayKay,

Thank you for writing to Microsoft Community Forums.

Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol, or if there’s software installed on your PC that’s disabling
Teredo functionality. If you haven’t tried the methods listed in the following articles yet, I would suggest you to try them first and see if it works:

• Teredo is unable to qualify
  
• Xbox app server connectivity on Windows 10 is blocked
  
  

Note:

Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry
if a problem occurs. To backup and restore registry key, refer to this
link.

If the issue persists, I would suggest you to
uninstall and re-install the Xbox app to see if you can get it to work.

• Right click the Windows icon on the taskbar and choose Windows PowerShell (Admin).
• Copy and paste the following command and hit Enter:
  
  Get-AppxPackage Microsoft.XboxApp | Remove-AppxPackage
• Reboot the computer once the command is executed.
• Once the machine restarts, launch Microsoft Store and reinstall the Xbox app.

After reinstalling the Xbox app, open Windows PowerShell (Admin)
again and copy paste the following command to enable Teredo.

netsh interface Teredo set state type=default

Let us know how it goes.

Regards,

 

XBOX App - Teredo is unable to qualify

Hey there Velix. While I do not know what fixes you may have tried, xbox has listed some here:

https://support.xbox.com/en-US/xbox-on-windows/...

If you are getting the error "Teredo is unable to qualify: then your PC cant obtain a Teredo IP address.

There are many fixes listed on that site. If the fixes listed her do not work , I may have more solutions as I have had the same issue myself. What fixed it for me was simply waiting until it finally worked. Contacting your ISP might help as well.
