Fallout 76 No reigon ping Error on xbox series X

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today No1inpaticular

Please answer the following questions :

Are you receiving an error when you try to install the game again?
Or the download simply doesn't start?
Which region do you have selected on your Xbox Console?
If you try downloading another game, works flawlessly?

In the meantime try this to see if it do the trick:
1. Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.
2. Unplug the console's power cable from the console and from the power outlet. Wait 5 minutes.
Important: Be sure to wait at least 5 minutes. This step resets the power supply.
3. Plug the console power cable back in.
4. Press the Xbox button on your console to turn it on.

Aftert that, try to remove and re-add your profile on the console.

In case you need it, here's how to remove and re-add:

Also, disconnect your router from power for about 3 minutes and try again once everything is up and running

I'll be waiting for your answers, greetings from another Microsoft user!

That's strange, buddy please try changing your DNS first:

go to Settings > Network > Advanced Settings

Once you’re inside the Advanced Settings menu, go to DNS settings and select Manual from the list of available options.
When you get to the next screen, enter 8.8.8.8 in the box associated with the Primary DNS and 8.8.4.4 in the Secondary DNS box.

Once the default DNS addresses have been changed, restart your console and see if the issue has been resolved at the next console startup.

------

If the issue persists, please try connecting your console momentarily to another wifi network
(If you're able to do it, share mobile data via wifi hotspot and connect your console in that way)

Answer to the first question, I do not receive an error it just doesn't start.

Answer to the second, my region is set to eastern time

Answer to the third I find that none of my other games are launching or installing either.

I tried the thing you told me to do and I am still having the same issues.

Amazing!
I'm glad to hear that now everything's working as usual buddy

Take care, and happy gaming!

Thank you for replying, the situation is now resolved, it turned out to be an issue with my router settings. I appreciate your help.
