Windows 10: Xbox live Teredo in unavailable to qualify

I'm struggling to connect to xbox live on my PC. When I go to Xbox networking it says Teredo is unable to qualify. Server connectivity is blocked.

I've been through the help steps, tried the built in "fix it". No dice.

I suspect the issue is with my tcp/ip protocol driver as I couldn't find that when looking to see if the IP helper service was running I believe it was.

When typing in netsh interface Teredo show state to cmd prompt - Server Name : win1901.ipv6.microsoft.com.

Doubt its a router issue.

Any help is appreciated, thanks in advance :

XBOX: Teredo is unable to qualify

Hi Will,

The Teredo is unable to qualify error means that your PC is unable to obtain a Teredo IP address.
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. Without
a Teredo IP address, you’ll be unable to use party chat or do multiplayer gaming on Xbox Live.

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

Hi Tony,

There are several reasons why the Teredo is unable to qualify for the Xbox app when connecting to Xbox Live. It is possible that the required network ports are not opened or the Teredo Tunneling Adapter is not updated or installed on your PC. To resolve
your concern, we suggest that you perform the following solutions:

Solution 1. Uninstall and reinstall the Teredo Tunneling Adapter.

• Press Windows + X on your keyboard and select Command Prompt (Admin).
• Type the following command: netsh interface Teredo set state disable
• Hit Enter.
• Press Windows + X on your keyboard again and select
  Device Manager.
• Select View > Show Hidden Devices.
• Click on Network Adapters.
• Look for the adapters that contain Teredo such as Teredo Tunneling Pseudo-Interface or
  Microsoft Teredo Tunneling Adapter.
• Right-click on the adapter name and click Uninstall.
• Restart your computer for the changes to take effect.

To re-enable the Teredo adapter:

• Press Windows + X on your keyboard and select Command Prompt (Admin).
• Type the following command: netsh interface Teredo set state type=default
  

Note The Microsoft Teredo Tunneling Adapter will reinstall automatically. It is not recommended to install the
Teredo Tunneling Pseudo-Interface adapter in the Device Manager because it may cause issues with the Teredo functionality.

Solution 2. Open the network ports using port forwarding.

There are possibilities that your network hardware or firewall might be blocking communication with the Xbox Live servers. Please refer to this

link and follow the steps under Part 1: Set a static IP address, or switch to manual IP settings,
Part 2: Open ports on your router or gateway, and Part 3: Set a static Teredo port.



If you need further assistance on configuring your router settings, you may contact your router manufacturer.
