I cannot connect VPN by PC in China

Hi I am in China now and can connect VPN by my iPhone. It is fine 3Mbps is acceptable, but I cannot connect from my Windows PC. I have tried lots of location but failed. Does someone has similar issue ever?

same issue. Want to know when I can use on Windows.

change port setting to manual and put some random number, atleast it worked for me

the solution just worked for one time.I cannot use it .again.my feelings
get hurt.
