I now have reset my modem and router five times, verified no change to firewall, reinstalled the game 4 times. Restored license 3 times. Game masters have reset my Battle net account. I am still receiving a Warning box with "There was a problem logging in. (Code 1001). I have no idea what to do next. A friend recommended a region change from North America to Japan since I am military abroad. But I have been playing no problem for a year here until the last 7 days that I have been locked out. Please help! I want to play the expansion but this has made the game period unplayable.
I get the same thing. You get any help yet?
Not from blizzard or my isp. However I figured out it was my ISP fault and was able to put a VPN on my PS5 primary DNS and backdoor my ISP issues
