I just want to install Let's encrypt ssl on new CNAME that I just added on digital ocean server.
E.g my cname is insights.example.com. The main domain is already install SSL. I just want to install only this cname domain. Please help me which command do I need to run.
Step#2 could be: sudo certbot --apache -d insights.example.com
OR sudo certbot certonly -d insights.example.com
[this method would require TLS file creation]
OR
[other valid subcommands and maybe some additional steps]
