How to check the certificate on the origin server?


I can see the cloudflare certificate when I view the certificate but how to I check the one on the server behind cloudflare?


You can unproxy the record, pause Cloudflare altogether, or use any other means to connect directly to your server (e.g. hosts file).

Try this command, replacing the text for your origin.

openssl s_client -connect <Origin IP address>:443 -servername <SNI Hostname>
