However, you should keep in mind that whenever Blizzard Entertainment releases any new seasonal content or patch update to the base Diablo IV game, the server downtime or maintenance schedule may go through for some time.

Fortunately, here we’ve shared with you some of the potential workarounds that should come in handy. Make sure to follow all methods until the problem has been fixed.
