How can I fix this problem on my Xbox?

I have a Xbox one X. Some time last month.

Got it. Let me know if you've tried all my suggestions above. Thank you!

Hi there!

What exactly is your Xbox console model? When did the issue start to occur?

Try to test your connection:
Press the Xbox button to open the guide.
Select Profile & system > Settings > General > Network settings.
Select Test network connection, Test Multiplayer, and Test NAT type.

Let me know what are the results.

To further isolate the issue, try to connect your console to a different network like your mobile data hotspot.

Try to reset your router as well by unplugging it from the power source and wait for at least a minute before turning it back on. If possible, connect your console through wired connection.

Heya, let's try refreshing the profile by
removing it then adding it back to the console. Once this is done, check if your subscription is working as normal. If it is not, please reach out to our
chat/phone teams so they can take a deeper look into the account and subscription.

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

I'm sorry to hear that you're having trouble accessing apps, games, and other tools on your Xbox. The error code 0x8027025a can be caused by a variety of issues, including problems with your internet connection or issues with the Xbox itself. Here are a few things you can try to resolve this issue:

Restart your Xbox. Sometimes, simply restarting your console can resolve issues with apps and games not loading. To restart your Xbox, go to the "Settings" menu, select "System," then "console info & updates," and then select "restart console."

Check your internet connection. Make sure that your Xbox is connected to the internet and that you have a strong, stable connection. You can check your connection status by going to the "Settings" menu, selecting "Network," and then selecting "Network settings."

Check for updates to your Xbox and to the app or game you are trying to use. Sometimes, updates can fix bugs or other issues that might be causing problems with apps and games not loading. To check for updates, go to the "Settings" menu, select "System," then "console info & updates," and then select "check for updates."

Try resetting your Xbox. If none of these suggestions help, you can try resetting your Xbox to see if that resolves the issue. To reset your Xbox, go to the "Settings" menu, select "System," then "console info & updates," and then select "reset console."

If you've tried all of these steps and the problem persists, it's possible that there is a more serious issue with your Xbox.
