Previously I ran Let’s Encrypt just fine before and ran into problems when I had to renew. So i started to look into Origin Certificates.
But i seem to be getting an issue when I apply the Full(Strict) mode. I had successfully installed the certificate on my hosting server (At least I think I have.)
- I let Cloud Flare generated the private key and CSR, then input that into my cPanel.
- For the CABUNDLE certificate I found a link which I copied (https://support.cloudflare.com/hc/en-us/articles/218689638-What-are-the-root-certificate-authorities-CAs-used-with-Cloudflare-Origin-CA-) .After I put this in, I then received a message saying I have installed the certificate etc. With all green ticks.
If i attempt to refresh the page without CloudFlare active i get a NET::ERR_CERT_AUTHORITY_INVALID message.
If I turn on cloud flare Full Strict or Full it suggests that my Host is down or Invalid (502 error)
If i turn on flexible mode it works fine.
Any suggestion to what I could be doing wrong?
