Doubt why one of my web does not have an RSA certificate

Why do other sites have RSA certificates but the main domain name does not…

It looks like your domain is in a non-standard configuration.

Are you using Cloudflare’s Chinese CDN setup?

Other than what you see in the certificate, is something not working?

Really thaks for your reply(~ ̄▽ ̄)~!

Yes, I’ve add this domain through Plesk server and managed it by partner. The difference with other resolution records is that this root domain name conflicts with the MX record, so I directly point to the IP assigned in Partner.

I think I should try to connect the CNAME to the CF when I have the opportunity, but I am worried about some interruptions, because the CF service is not fully used.

It’s not a serious problem, I just confused about it hahaヾ(≧▽≦*)o

This needs to be fixed. It’s not a good idea to point an “A” record at a proxy address when that hostname isn’t proxied.

The MX record doesn’t even point to your domain.

Thanks again for your help!ヾ(≧▽≦*)o

With your reminder, I understand that the CNAME of CF can inherit MX and TXT records, so I can safely point to the CNAME of CF.

The network environment in Mainland China is relatively special and it is far from the edge nodes, so I have to use some services provided by local providers in China. Therefore, through the service provided by a specific DNS service provider, the mainland and overseas resolve to different service providers.

Now this problem is solved very well, happy!
