Certificate issue everyday

Cloudflare has observed issuance of the following certificate for theholidaystory.com or one of its subdomains:

Log date: 2021-11-17 03:12:03 UTC
Issuer: CN=R3,O=Let’s Encrypt,C=US
Validity: 2021-11-17 02:12:02 UTC - 2022-02-15 02:12:01 UTC

I get this message every day. But unable to find subdomains. Please help me to find

There’s no “DNS Names” after this line?

DNS Names: *.theholidaystory.com, theholidaystory.com

You currently have a security issue.

I am unable to understand your point.

Please guide me what to do.

Subdomains are covered by the * in that first hostname.

Doesn’t sound like there’s an issue, instead it sounds like you may have subscribned to Cloudflare’s certificate transparency monitoring. https://blog.cloudflare.com/introducing-certificate-transparency-monitoring/

I don’t have any running subdomain. That is why I create this ticket. Need to find why the certificate is issued and where it is used. your kind cooperation is needed.

As @cs-cf said, it looks like you subscribed to Cloudflares CT monitoring.

You can see the certificates issued for your domain here:


You should investigate who is issuing those certs on your behalf. It could be your hosting provider, who is ensuring you have a valid certificate on your Origin. (This would enable you to ensure you can set the SSL Mode to Full Strict, if that is not already the case).

It turns out that you do. ‘www’ counts as a subdomain, and that’s the URL your site uses.

Thank you Mr Michale for the link.

I don’t think my provider is doing this. Last time my site was attacked with a virus and created a subdomain automatically. The problem was solved at that time. That is why I am a little scared about this case.

As for that I can really point to the article again.

Dear Sandro
If I am that technically sound, then I don’t come here and seeking for help.
