Does this mean that i need 2 certificates or i just need what you have posted only ?

A Cloudflare Origin Certificate is the equivalent of a Self-Signed certificate. It’s designed for servers sitting behind Cloudflare.

Why aren’t you using Let’s Encrypt, or some other generally accepted certificate?

The error message told you to also install the intermediate/chain certificate. The link I gave you contain the chain certificate. You’ll need to install it alongside the certificate Cloudflare generated for you.

Once you install the certificate, please set SSL to Full (Strict) mode at Cloudflare Dashboard.

This is driving me crazy ,i have tried all things but i still have insecure https prompt .Below is test results from ssl test.

I am able to load your site correctly without any warning. The test results you posted shows no problem and also grades your site with an A. You shouldn’t get any HTTPS error on

Strange thing is that when I try to acces the site using chrome on my pc I get a NOT SECURE

Thank you very much. I had to wait for almost 24 hours on my end before the browser resolved the HTTPS. I can now confirm that the SSL has a green lock and no security prompts.

If you receive this error, it means you are not being protected by Cloudflare.

Cloudflare’s SSL only works when your website’s traffic goes through Cloudflare. The “Cloudflare Origin Certificate” is a certificate that is only trusted by Cloudflare, not by browsers.

To fix this:

  1. Go to the DNS tab in the Cloudflare dashboard
  2. Find either the “A” or “CNAME” record for the subdomain you have this issue on
    (if this issue occurs without a subdomain, find the A/CNAME DNS record where the “name” is your website, eg.
  3. Make sure that DNS entry has a cloud icon on the right is an orange cloud :orange:. Cloudflare’s SSL DOES NOT WORK if the cloud is grey :grey:. If the cloud icon is grey, click it to turn it orange.

Your website should now be going through Cloudflare and Cloudflare should be presenting a valid SSL certificate.

With this, you may get either a too_many_redirects error or another SSL error. To fix this, make sure your “SSL mode” in the SSL/TLS app is Full (strict). This is required when you install the “Cloudflare origin certificate” or another SSL certificate on your server. If this doesn’t fix it, see Community Tip - Fixing ERR TOO MANY REDIRECTS.
