Usually, this error is related to app corruption, network issues or server related problems.

In order to fix this issue, here are a few solutions that you can use.

1. Verify the Xbox server status

Before attempting other system fixes, you should make sure that the Xbox servers are up and running.

There is no need to resort to making system changes if the Xbox servers are down. You’ll just need to have a little patience.

Go to the official Microsoft web page to check the live server status.

Check the server status on DownDetector in order to see if there have been recent issues with the server.

3. Test and improve your internet connection

  • Perform a test on your internet connection from the Xbox settings to make sure that your connections are working properly
  • Hard reset your router/modem
  • Run a wired connection instead of a wireless connection, it’s usually faster and more reliable
  • Contact your ISP and let them know if you’re internet is running slower than usual.

5. Contact the Internet Provider

Sometimes, you could have some closed ports blocking your access to certain internet portals.
