Hello. I’m getting this error when attempt to log on without already being logged in to the Battle.net client. The info page for the error suggests that my input is incorrect for user/password, but they are correct. I’ve tried with a PC where I am logged in to Battle.net in the launcher and it works fine there, with the same credentials as I’m attempting to use without the Battle.net login.
I guess my problem is similar to these threads, I was unsure whether to post a “me too” in one of those or create a new thread:
