What I’m seeing is that I can’t install/add the Cloudflare generated Origin Certificate into my domain in cPanel, I need to add it so I can use the “Full (strict) encryption mode”.
I’m using this software: InfinityFree Free hosting plane, cPanel, and Cloudflare.
Cloudflare’s Origin Certificates are not valid certificates. Cloudflare is not a recognized SSL vendor, so their “Origin Certificates” cannot be uploaded. To use Cloudflare on your site, you can configure Cloudflare to use “Full” SSL mode in conjunction with the default certificate, which also ensures your connection is encrypted the whole way. If you insist on using “Full (strict)” mode, you must use a regular SSL certificate for your site instead.
