OS : centos 7 (from vultr : selinux off )

I want to description my case completely here.

The following are the 2 different subdomain which set in my dns record ( A record is pointing to same server, act as 2 domains)

hostname : server.mydomain?com
another domain : sucms.mydomain?com

Steps :

1. complete install cyberpanel, found some warning, but whatever, I can access from :8090
2. my first part is go to hostname ssl generate the ssl, it is success : SSL Issued. You can now access CyberPanel at: https://“domain”:8090
3. then I go to the above domain to test if the cert if working, result : NOT WORKING
4. then I go to add website (my another new subdomain), of course choose SSL option, WORKING
5. remove the hostname from website list, found I cannot add it back, because it is blacklist in hostname
