Hi , my name is Fernando. I'm a gamer like you who loves to help other gamers with their Xbox questions. I can help with most questions. However, I do not have access to your account details to provide billing information/account inquiries. Thank you for reaching out to the Microsoft Community.

Try this procedure:
Turn on the console. Test your connection again (Profile & System > Settings > General > Network Settings > Test Multiplayer Connection).

If it doesn't work, you may be facing a problem with the game. You need to submit a ticket with the Minecraft Help Center using the link below.

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.
