I have a Wordpress server hosted on AWS EC2 and accessed through Elastic Load Balancer. The ELB is using AWS ACM authorized certificate.
However, when I select the “Your SSL/TLS encryption mode” on my Cloudflare dashboard, I can only select “Full”. If I select “Full (strict)”, I get Error 526 Invalid SSL Certificate when visiting my website.
I am confused by the description of “Full (strict)” mode “Encrypts end-to-end, but requires a trusted CA or Cloudflare Origin CA certificate on the server”. Is AWS AMC authorized CA not considered trusted CA in Cloudflare?
What exactly does “trusted CA” mean here?
