Invalid SSL 526 (I am going crazy)

So I am going this Invalid SSL certificate Error code 526 error only when I use Cloudflare's recommended Full (Strict) mode on SSL.
Please note that the SSL I use was created on Cloudflare > my website > SSL/TLS > Origin Server > Origin Certificates and I used that certificate on my controlpanel (aaPanel) successfully but I keep getting this 526 error when full strict is turned on.
When I switch to full or flexible then the website is reachable.

What am I missing? what am I doing wrong?
If it helps, I am using Ubuntu server on Digital Ocean and all the domains have the same issue.
