Asked by imj

Hi,

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 https://support.cloudflare.com/hc/en-us/articles/115000479507 https://www.digitalocean.com/docs/spaces/how-to/customize-cdn-endpoint/

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: https://www.sslshopper.com/certificate-decoder.html

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