Hey! I have the same problem now : the black screen after loggin in. In the past, when I was playing the game, it worked (I have the same isp provider).
The same problem i have it on my laptop, so its not a PC problem. besides, when I connect to the interner via Data connection (3G/4G via phone) I can connect to the game, and actually play.
things I tried:
*remove the router from my "network", doing a direct connection (modem).
*the DNS- workaround
*my ip address (dynamic): 18.104.22.168 (romania) - the unworking ip :)
Please reply if there is others things/ideeas to try to connect to the game, OTHERS that the VPN...thing.
have a nice day !
