Can you visit any other website while connected to the VPN? If you can, try flushing the windows DNS cache. Open an elevated command prompt, run "ipconfig /flushdns". Then reboot your PC and reconnect the VPN. Also try a different web browser.

Where is your VPN server located? Is it in China? Can you also reboot your VPN server (to clear the DNS cache) and try again?

[ilaziness]
