Hello, I've been getting this problem within the last few days.

Country: Australia
ISP: Primus
Happens: very randomly, I can log in days without any problem. Then the next day all I have are problem, reset PC, reset router, restart game over and over and nothing will fix the problem, just have to wait it out till it fixes itself..

I some times use a VPN service just to be able to sit around and chat with friends, but the game is not playable through the VPN as it just increases the lag and cant run out AOEs and the like.
