Hello.

I'm in Hong Kong, and the Internet can access zoom.com . But I can't access the registration page.

My ip is 103.166.175.129.

Please confirm what the problem is? How can I solve it?

the prompt is:

Sorry, the country/region you do not support free users.

But I change another IP cat access the web page.
