It says "you appear to be in a region where this service is not available"

That's a good idea I'll try it with my phone and see if that works

I’ll remain attentive to any other inquiries you may have, Tony.

Have a good day!

Yes I checked this out first of all. Everything has and was working ok and just suddenly stopped.

I'm in the UK and am using Hey Broadband for ISP and it turns out they've messed up settings and I'm having to wait until Monday for them to reset IP addresses to correct my region settings.

Hello Tony, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

Let’s try to sort this problem out. However, I would like to ask some questions:

Where are you physically located? Your country.
Please review if your Microsoft account and Xbox country are the same as your location.

You can review the country for your account here:

On Xbox, you need to open Settings > System > Language & Location.

Hi, Tony.
Would be great to wait until your ISP can assist you with the IP address reset.

Meanwhile, you can try verifying if the same error message appears when you use a different internet source.
If you’re able to do it, you can test this by enabling temporarily your phone’s mobile hotspot.
