Areas in China thought to be inaccessible

What is the name of the domain?

What is the error message?

ERR_SSL_VERSION_OR_CIPHER_MISMATCH or DNS resolution is not effective

What is the issue you’re encountering

After purchasing a domain name in Aliyun, use Aliyun DNS for China region and Cloudflare DNS for other regions, you can access it normally in China region, but when you use VPN to change the address to Hong Kong region to access the website, there is an error of “ERR_SSL_VERSION_OR_CIPHER_MISMATCH MISMATCH”, clear browser cache and then “DNS resolution invalid” error appears when changing to US region!

What feature, service or problem is this related to?

I don’t know

That’s not going to work. Your nameservers are currently Aliyun, not Cloudflare and your Aliyun DNS contains CNAMEs that point to the Cloudflare nameservers.

You can have your domain use Aliyun, or Cloudflare, but not both.

The only simple way to do what you want is to have different domains for China (using Aliyun nameservers) and the rest of the world (using Cloudflare nameservers), and redirect between them based on country detection. There may be some custom setup you can do with Cloudflare’s China network offering, but that’s going to cost.
