How do I enable Teredo?

If your nat type is open just reset your router, if not do some research on how to fix it. I get the same problem I just reset my router and it goes away.

That's exact what I wanted. Thanks for sharing.

You have Teredo unable to qualify and server connectivity blocked. This can cause a lot of issues since you cannot connect properly with the Xbox servers.

Please click on "Click here for more information" on your connection test to try to make these two error messages disappear.

Also please do:

If you are running Windows 10 Pro please follow these steps:

Press Windows + R, type gpedit.msc and press enter;

Under Computer Configuration > Administrative Templates > All Settings

Find "Set Teredo Client Port" , "Set Teredo Default Qualified" , "Set Teredo Refresh Rate", "Set Teredo Server Name", "Set Teredo State". Change these settings like below:

Set Teredo Client Port - Enable - input " 0"

Set Teredo Default Qualified - Enable - choose "Enabled State"

Set Teredo Refresh State - Enable - Choose "30" or "20"

Set Teredo Server Name - Enable - input "win10.ipv6.microsoft.com"

Set Teredo State - Enable - choose "Client" (If after doing all steps it fails, try choose Enterprise Client instead.)

Then follow the steps on the Xbox website for both issues, restart your computer and see if your connection result shows Open NAT and connected to server.

Let me know how it goes, please.

What I did to fix the Teredo issue on my Windows 10 Pro was:

- Press Windows + R > Type gpedit.msc and press Enter.

- Go to Computer Configuration > Administrative Templates > Network > TCP/IP Settings > IPv6 Transition Technologies. Change the settings like below:

- Teredo Client Port - Enabled - input " 0"

- Teredo Default Qualified - Enabled - choose "Enabled State"

- Teredo Refresh State - Enabled - Choose "30" or "20"

- Teredo State - Enabled - choose "Client" (If after doing all steps it fails, try choose Enterprise Client instead.)

See how it goes and please let me know. I can't say for sure that it has an impact on party/social services, but since it can block your connection with the Xbox servers it might be the culprit here.

I have the same issue. Destiny 2 will not work with multiplayer. Tried all the teredo suggestions. Does the game use Teredo and do i have to enable IP6 on the router side to make Teredo work?

Performing a port forward works at times, yet some home routers will block Teredo connectivity if they detect that an IPv6 connection is present on the WAN interface of the router. For Teredo to function normally,
the router needs to be configured to enable Teredo connectivity. If you have one of these home routers, make sure it has the latest firmware, and see the support documentation to determine how to enable Teredo tunneling on the router.
