Diablo 2 Resurrected server maintenance is now happening. If you were wondering why you can’t connect, well that’s your answer. This downtime will apparently help them fix the “character lock” problem.
As we approach the deploy time (10:30 AM PDT), we recommend that you log off prior to the servers restarting to avoid losing character progress.
While this is an important issue to resolve, I have no idea why they have not done this overnight instead of the daytime when people want to play.
