how to solve teredo is unable to qualify, i tried everything and the problem is not solved

Hi Ezzel,

Have you tried the below steps?

NAT type on Windows 10 displays "Teredo is unable to qualify" | Xbox Support

Kind Regards

Tried this,

On the Xbox networking window in settings, Xbox Live Multiplayer does say that Teredo is unable to qualify,

when I hit Fix, it doesn't solve the problem.

running the query in solution 3 in the troubleshooting, my output in the cmd is:

REG_DWORD 0x1

Which looks like Teredo is not disabled

Seems to be some other issue

i had this issue all the time, I solved it by the following:

go to services.msc

scroll down until you find IP Helper, Click the option to restart it.

Then go to ip translation configuration (should be directly below ip helper) and choose STOP on this, You can also permanently disable this by right clicking, selecting properties and then set startup type to manual.

This works everytime for me, None of the command prompt stuff would work to resolve the teredo nor did uninstalling the teredo adapter, Haven't had an issue with it for a long time now since doing the above method, Also worked for my brother first time.

hope this helps

Hi Kerem001!

Thanks for your post, if Teredo is still unable to qualify with all steps taken, it would be good to verify that the router used to connect your PC to the internet has teredo tunneling enabled. If the teredo protocol is not enabled or supported by the router
it could be causing the issue. I recommend going through the router's manual or contacting the manufacturer for a possible firmware upgrade for Teredo tunneling support.

I hope this information helps, thanks again!

Hello DriftingBrandon,

Thank you for keeping us updated. The teredo error has to do with a connection issue between Xbox Live and the home network. Forza updates will not resolve the issue. We recommend attempting the troubleshooting steps on

Forza's Support Page in order to resolve the issue. The details of a refund must be discussed with the
Xbox Support Team. There is an article on our website entitled

Request an Xbox Digital Product or Subscription Refund that Xbox users can use to request a refund. Be sure to let us know the results!
