  2. 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.

    To resolve your concern, you may follow the provided solutions on this
    link
    .

    If the issue persists, you may perform the additional troubleshooting steps provided on this

    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:


    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,
