Windows 10: Teredo is unable to qualify (networking or xbox live error)

Hi friends,

I bought the xbox game pass for PC yesterdayand tried to play Sea of Thieves however I could not connect to xbox live!

I checked Xbox Networking and received the notice: Teredo is unable to qualify & Server Connectivity: Blocked.

I used the fix it option, updated windows, restarted, reinstalled, followed the Microsoft help guide all with no success. I also restarted my router, still no dice.

My friend who has a bit of experience in networking couldn't figure it out either, but he's confident its not my router blocking access.

One thing I noticed is that when I go to manually reinstall or update Teredo, through Device Manager>Network Adapters>Add Legacy Software I can't find anything to do with Teredo and the guides I've looked at say that's the way to do it/ it should definitely be there.
I've posted this on the Microsoft forum, but have received no reply. Please help me solve this mess!

Thank you 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.

To resolve your concern, you may follow the provided solutions 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:

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:

Packet Loss : Blocked

My NAT type says "Teredo is unable to qualify"

Hi Kole,

You may receive the error message Teredo is unable to qualify
if your PC is unable to obtain a Teredo IP address. Teredo is a networking protocol that’s used to establish secure communications between clients and servers and to facilitate connectivity between devices behind routers that use network
address translation (NAT). To resolve your concern, we suggest that you follow the steps provided on this

link.

If you have already done those steps as you mentioned in your description, you may proceed to open the network ports and setting a static Teredo port by following the steps on this

link.

Keep us updated with the results after performing the suggested solutions above.
