DNSSEC is not working on my Domain (.com)

My domain registered in Aliyun.com, and I tried to enable the DNSSEC following everything with the tutorial, and indeed, all of the settings passed the testing, still, the site can’t be accessed, how to fix?

By the looks of it you’re not using Cloudflare:

https://dns.google/query?name=aliyun.com&type=NS&dnssec=true

As for the issue, you can test at https://dnsviz.net/d/aliyun.com/dnssec/ - there’s no DNSKEY on your nameservers.

aliyun is my domain registrar, and what I got the problem is on lueei.com, thanks for your reply.
