A BC-124 error code means that there is a connection problem between your Xbox and the game servers.
While it could be caused by a problem with your own network connection, it’s also quite common for a BC-124 error to occur as a result of an update to either your Xbox or the Overwatch game itself.
A BC-124 error can have several causes, and below you’ll find several steps you can take to try and resolve the problem.
What causes a BC-124 error on Overwatch?

There may be several reasons for the error. You may have a bad internet connection. Another reason is that you need to install an Xbox update or update your version of Overwatch, otherwise your connection will not be authenticated.
