I got the above mail 3/4 times today. I can not found any certificate in my Cloudflare account. what to do? Please help Team


Hi there @holidaystory17!

Sounds like a certificate transparency monitoring notification. From your Cloudflare Dash, take a look at your SSL/TLS > Edge Certificates section and look for the Certificate Transparency Monitoring option.

Here’s this article for more details regarding this: Certificate Transparency Monitoring · Cloudflare SSL/TLS docs

Hope this helps!



Thanks for Replying Blas

When I got the Cloudflare mail, I immediately check all the subdomains and found one certificate is issued for a subdomain, but pointing to a different domain. That’s strikes me.

Yes, one certificate is in the Edge Certificates section.

Looking for your valuable opinion.

I do see your domain listed for new certs issued by Let’s Encrypt. For your site, Cloudflare is issuing its own certificate through DigiCert.

My guess is your host has renewed the certificate for your site on your server. This is “a good thing” since it’s important to have a valid certificate on your server. Have you asked your host about this?

For the FTP site, that’s going direct to a server that has a certificate installed for a different domain. Regular FTP doesn’t care about certs, so this shouldn’t affect you.

Hi there,

Check the proxy mode for this particular subdomain as it appears to not be proxied through Cloudflare.

Note, that this DNS record may have been configured this way in order to have FTP function properly.


The certificate you are seeing is from the origin server itself. Only DNS records that proxy through Cloudflare (orange cloud) will have your Edge certificates applied.

Here to help if you have further questions :slight_smile:

So, I am not doing anything for now. Thanks for your time.
