I installed Cloudflare Origin CA Certificate on the origin server via the cPanel. It expires after 15 years. On Cloudflare, I then changed the SSL/TLS encryption mode to Full (Strict). However, the website is still showing the Cloudflare certificate expiry date as July 2021.
My guess is that the expiry date of the website cert is actually the expiry date of the universal Cloudflare SSL, which will auto-renew in July. Would that be correct?
Then, how is the other certificate that I installed on the origin server going to be used?
