I know there are already topics about this but none of them have solved this issue for me on getting past the lions gate. This started for me a week ago for absolutely no reason at all.
I made sure I have no firewall on, im not on a PTR, I have uninstalled and re-installed the game, I uninstall and reinstalled battlenet. and all the other suggestions with messing with the shortcut…nothing works…this just started up…any fixed that have not been mentioned previously? again, I went over all the other post on this subject and none of the recommendations worked.
Do you have a different machine you can test on? does the game work with the same account on a different machine?
