Any idea why recaptcha works in almost all countries except at least one in particular?

[jcun...@gmail.com]

I thought it might have been an ISP caching thing, I was having this problem on my end with regard to making changes to a server I rented. I kept refreshing/empty-hard reset but couldn't see the new changes. This isn't behind a CDN at least not something like CloudFlare where I have control of it, it was just a cheap shared hosting server.

Anyway, I used Tor to get an external view of the site (as well as external waterfall flow) to check out the site elsewhere (now taking about recaptcha) and it was working. It was just odd that in Australia it kept showing a domain error problem. 

The recaptcha domain list has all of them and it doesn't use the www version of the domains.

It uses aliases (all in the recaptcha list) and the same template.

It's just odd that Australia (relevant due to deployment location interest) is the one place that domain error kept coming up.

Any thoughts?

Make that 2 countries.

I have a server in China and ReCaptcha doesn't work on the server too. It always says that the host is unreachable. Tried pinging the Captcha IP address too but couldn't connect.
