Diablo 4 Season 3 officially started, but even if the base game has been released for a while now, players are still getting the “Unable to find a valid license” error code. Players who encounter this bug aren’t able to log into the game, and the Battle.net description doesn’t clarify what’s happening to Diablo 4 servers.
