Certbot

Certbot failed to renew certificate to all domains hosted in a particular server. While most of the servers shoot the bot to acquire the certificate, it bug me why some didn't when they have the same setup. I guess because a domain or two in those failed servers are using premium SSL, but I am not sure honestly.

Certbot will let you manage your SSL certificates, ensuring that your server will automatically renew Let's Encrypt without you doing it by hand.
