The authentication of credentials error is still persisting even after the EU and USA server are up and running. I had this in the beginning a few hours back, and it's no different now.
I try to log in with my Battle.net e-mail and password. I also am using a guest pass (on my account info apprently stating it's for the USA region) and have tried logging in on all regions. I myself am based in the EU. The whole time this reoccurring error. Might this be a more deeply rooted problem that is account specific?
Appreciate any help.
