HelllooOOOOOOooOOooOooooooooOOOoOoo! After getting errors saying authentication failed for 1 week now, i figured out why not try something that havnt been mentioned in the "help" posts earlier. The things you prolly have tried: added exceptions to firewall and antivirus latest .net framework added port newest hb version run wow as admin run hb as admin 32 bit direct x 9/11 windowed mode BUT HAVE YOU TRIED TO DELETE ALL EXISTING FILES ON YOUR COMPUTER FROM HONORBUDDY? (maybe you have a second hb folder on your computer that is fucking it all up, like i had) My reason for getting these errors was because i had a hidden old hb folder. I deleted it all, and downloaded a new fresh one. And boom, it worked. I hope this may help some of you Enjoy MOP!
