it says "U cant enter the server" , it doesnt say why.

well just translating what it says, kinda hard to figure your problem out other then u cant enter the server.
I assume u using a VPN if ur not in russia

I'm currently getting the same bug. I get it with or without a vpn. So it's not too likely to be a IP block issue. Admittedly SoftEther vpn is producing some pretty weak Russian vpn sources. But it is still connecting to Russian vpns. So I'm pretty much stumped as well.

Ok here's a update. I went just to be sure and purchased Pure VPN. Even with using it I run into the exact same problem. I would be really nice to know the why of this issue. I've since checked my email. There is no notification from the publisher since my original emails. So I know its not account related. I've also noted that both VPN clients quickly bottom out on speed to Russia. Could it possibly just be line noise?
