Are you by any chance using Cloudflare Workers? Responses created by a worker won’t include the Cf-Cache-Status header as Cloudflare Workers run before the cache.
Otherwise could you let us know the domain so we can take a look?
The subdomain www.easternwind.asia is pointing to Cloudflare’s IPs .
$ dig www.easternwind.asia +noall +answer
www.easternwind.asia. 14282 IN CNAME www.easternwind.asia.cdn.cloudflare.net.
www.easternwind.asia.cdn.cloudflare.net. 182 IN A 104.21.96.46
www.easternwind.asia.cdn.cloudflare.net. 182 IN A 172.67.173.3
But the domain apex easternwind.asia is unproxied .
$ dig easternwind.asia +noall +answer
easternwind.asia. 14214 IN A XXX.XXX.XXX.34
This is why the Cf-Cache-Status is not present in responses on easternwind.asia - the domain is simply not using Cloudflare. I hope this helps
easternwind.asia just has an A record (I presume pointing to your host). and www has the CNAME to Cloudflare. You will probably just want to configure a redirect from your root domain to www so that the traffic goes through the Cloudflare proxy on www.
