As Per this article https://kb.virtubox.net/knowledgebase/cloudflare-ssl-origin-certificates-nginx/
Then you will have to merge your origin certificate and the Cloudflare Root CA in a single file :
cat yourdomain-origin.pem cloudflare_origin_rsa.pem > yourdomain-crt.pem
after doing this i dont know what output should i get when i run it simply show me no such directory
can someone tell me what mistakes im doing
