Too hard because of the SSL certificate.
I created a CSR on the server as shown in Figure 1.
However, when you add it to the server, it changes to CN = CloudFlare Origin Certificate.
OU = CloudFlare Origin CA
O = CloudFlare, Inc.
The value has also changed.
The subject alternative name identifies my domain.
But I can’t use it like this.
How do I change the subject name?
