Sorry for the double post, please delete other post.
I initially had PD2 mod installed with D2:LoD and thought that was the reason, but after waiting quite some time with a clean install I still couldn’t log in to Bnet. I did see they share some of the same files though and wonder if that’s the reason. I do also have a VPN and wonder if I forgot to turn it off one time. Anyway, I guess I am hoping it is temporary and I don’t have to uninstall PD2 completely.
