Hey,
I created a new website in my dashboard for ssl certificates. Then changed the nameservers for Cloudflare. Everything is ok. Then I changed the SSL mode to Full (Strict). Then I create a new Origin Certificate and copy pasted to my server path ‘/etc/nginx/ssl/’. The original certificate name is ‘mysite-cert.pem’ and the private key certificate name is ‘mysite-key.pem’. After that I changed my nginx.conf file to:
server {
listen 80;
listen 443 ssl;
ssl on;
ssl_certificate /etc/nginx/ssl/mysite-cert.pem;
ssl_certificate_key /etc/nginx/ssl/mysite-key.pem;
…
}
Then reload the nginx but can’t reach the https url of my website. I can reach easily to http url.
website is : http:///
you can also check the https url.
When I tried to send request from postman it gives me this error : SSL Error: Unable to verify the first certificate.
I can’t send requests to this url 
Waiting for responses. Thanks.
Proxied by Cloudflare. Origin certs are only valid on proxied hostnames.
