Code Error 1021

I was playing Diablo 3 on my MBP 16 2019 with no issues. Yesterday, I reinstalled into onto a new MBP 16 2019 (similar device just new) and am unable to play at all. I keep getting “There was an error. Code 1021”. Yes, I did all sorts of troubleshooting, used different networks (mobile hotspot, WiFi, ethernet), I even tried my friend’s accounts and all. Nothing helped. I am starting to think there is something wrong with my BattleNet account maybe?

Hi :

Something’s happening… one player on the French forums says he can now connect to D3.
Hang tight !
