Update: It looks like the “Unable to find a valid license” error has started to pop back up again in Diablo 4 Season 3. In this case, it simply means the authentication and login servers for Diablo 4 are simply getting flooded and congested due to all the players trying to jump into the new season. Unfortunately, there’s not much you can do in this case. Just wait a few minutes and try again, and once the server congestion empties out a bit you will be able to connect without the error. This usually resolves itself within an hour or so after a new season launch!
