If there are issues signing in then "xbla_invalid" may be added to the end of the website URL. This can mean that there was a communication error or there is an outage. We recommend trying the steps below:
- Sign out if that option is displayed.
- Clear the browser cache and try signing back in .
- Try signing in with a different browser.
If this steps do not resolve the issue then there may be an outage. Please try again in a few minutes to check if signing in is working again.
If there are still issues, please contact our Support team with your gamertag or Steam ID, email address and the URL of the page you are signing in from.
