How to install a Let’s Encrypt SSL certificate for a domain in Plesk?

Note: Before securing a domain with a Let’s Encrypt certificate, make sure the domain name is resolved to a public IP address of the Plesk server from the Internet. If in doubt, check the domain name availability using DNS Lookup by MxToolBox.

1. Log in to Plesk

2. Install the Plesk extensions SSL It! and Let’s Encrypt

3. Go to Domains > example.com > Hosting Settings

4. Make sure the checkbox SSL/TLS support is enabled:

   

5. Go to Domains > example.com and click SSL/TLS Certificates:

   

6. At the bottom of the page, click Install in the section More options > Install a free basic certificate provided by Let’s Encrypt:

   

7. Select the desired options for the certificate to be issued. We recommend enabling the checkboxes:

   • Secure the domain name

   • Include a “www” subdomain for the domain and each selected alias

   • Secure webmail on this domain

   • Assign the certificate to mail domain

   

   Note: The specified Email address will be used to receive important notifications and warnings about the certificate sent by Let’s Encrypt.

8. Click Get it free

At this stage, a SSL certificate from Let’s Encrypt is generated and automatically assigned in Plesk to secure the domain. The certificate is valid for the next 90 days and will be auto-renewed by the Let’s Encrypt extension.
