Connection is not private for Spaces CDN with Certificate from Cloudflare


I am using Cloudflare to manager the domain, I add a subdomain cdn.<domain> to spaces cdn by Borrow own certificate, and I created ssl certificate on cloudflare for the this subdomain. However, it gives me the connection is not private when I try to connect to space cdn.

The steps I am following


Thanks Bobby

In order to make sure that this works you need to set the Proxy status for your CNAME to Proxied rather than DNS only.

Hi there @imj,

What I could suggest is decoding the SSL certificate to make sure that your domain name is correctly defined in there.

You could do that with the following command:

openssl x509 -in your_certificate.crt -text -noout

Or using an online tool like the SSL Shopper:

For example, if you are using you need to make sure that the www version of your domain name is also specified in the SANs of the certificate.
