Cloudflare cert doesnt apply

i have a site using letsencrypt ssl before, but two days ago i implementing cloudflare ssl. i checked the site and saw it still using letsencrypt ssl, why is that. my site is https://ngantre.com. thanks for helping.

Cloudflare does not issue certificates themselves. They use Let’s Encrypt and other CAs.


the left one is my testing vm, i have the same setup but doesnt ever using letsencrypt
and the right one is the vm currently i ask about. i expect the result is the same as my testing vm (left side) sorry, i dont understand yet

Cloudflare can provide Universal SSL certificates via a number of providers outlined at https://developers.cloudflare.com/ssl/ssl-tls/certificate-authorities

Cloudflare may issue certificates for SSL products from any of the following Certificate Authorities (CAs):

  • DigiCert
  • GlobalSign
  • Let’s Encrypt
  • Sectigo (formerly Comodo)

So looking at just the certificate isn’t enough. Check your HTTP response headers in your browser’s developer tools > network tab as well - should have a cf-cache-status header amongst other cloudflare headers
