This time I want to share how to update / renew the ssl certificate from Let's Encrypt because it is expired at the Hostname CWP (FQDN) Address.

CentOS Web Panel - Let's Encrypt
Example:
- Main Domain = lukmanlab.com
- Hostname CWP (FQDN) = srv.lukmanlab.com
The method is quite easy:
- Create a Sub Domain, according to the CWP Hostname (FQDN) address in CWP Client. Note: Usually the main domain has been added, only you can add the subdomain.
- Install AutoSSL to the Subdomain via CWP Client.
- Restart the Server.
Review:
Old certificates in /etc/pki/tls certs will be replaced with new ones automatically.
Thank you…
