In 17 years, never had this problem - very recent occurrence. Won’t update. Did everything that was suggested, and nothing works. Still get error. Since 18th, it also bugs out when I try and scan/repair. *Note: this is inconsistent also - I kept trying the other day and then finally got it to update, and then played for a while. When I logged back out last night, the problem started again.
I did manage to log in by using the app directly, and then authenticating manually. But I am unable to update anything for WoW retail through BNet launcher.
