Free Let's Encrypt SSL certificate installation

Now you can install a free Let’s Encrypt SSL certificate via the ISPmanager control panel.

This is a free SSL certificate that is issued after the domain name check (DV – domain validation). Its specific feature is that the certificate has to be renewed manually every 3 months. But ISPsystem has created a separate module for the ISPmanager control panel, which renews the certificate automatically 7 days before its expiration date.

The certificate is installed in 6 steps

1. Log in to the ISPmanager panel as the root user.

Subdomains are not supported
If you need certificates for subdomains, have a separate certificate issued for each of them.

Automation is supported only for one domain
One certificate can support up to 100 domains, but the automation process does not allow using one certificate for multiple domains. Have a separate certificate issued for each separate domain, or order one of the paid certificates with subdomain support.
