I try to get Cloudflare work with my website.
I have my website running on port 80 and my api on port 8443.
My proxy doesn't have a ssl certificate, I rely only on the one on Cloudflare.
I have set ssl to flexible.
I can access my website, but when I make an API call to my api on port 8443, I have the following message : CloudFlare is unable to establish an SSL connection to the origin server.
Do I need to have a certificate on my proxy for the API ?
Thanks for your help.
It sounds like you're using Cloudflare's Flexible SSL option whereby traffic is unencrypted to the origin web server (but encrypted from Cloudflare's Edge to the end-user).
This setting will only work for port 443->80, not for the other ports Cloudflare supports like 2053 (or 8443 in your case).
If you want to serve SSL traffic through a port other than 443, you will need to ensure your web server is configured to work with Cloudflare in either Full or Full (Strict) SSL mode.
