same here after rastakhan patch.
i have tried different copies of windows (10,8,7) but my problem still exists.
i connected to another ISP, my problem solved afterward.i can connect to main ISP using VPN, but lots of Timeouts have occured.
i found out that problem was from ISP.Bot server accessibility has been limited by my ISP. Now i want to check if there is another server, how can i connect to it?
