Hi, If you can provide some additional information we can try and diagnose the issue.
Xbox 360? Xbox One ? (Xbox 360 is no longer supported, if that is the device you are using, that would be the issue)
What happens when you try to open the app? Are you able to sign in and then you get
the error? Are you getting the error after you sign in but before the guide loads?
Are you having trouble with connectivity? Is the Xbox hardwired or wireless?
Are you able to use the app on other devices?
