Can't connet in China

I bought vyprvpn yesterday and when I am trying to use it in win10, it can’t connet, then I contact vyprvpn customer sevice, they provide me several ways to do, but all didn’t work.
I tried an another PC(win10), still didn’t work.
But it can be conneted in ios and mac os in the same network.
