Let’s Encrypt is a free, automated SSL certification authority. Using Let’s Encrypt is a quick and free way to get an SSL certificate for your website. With Plesk, you can create and deploy a Let’s Encrypt SSL certificate in just a few clicks.

Prerequisites

  • A cloud server with Plesk Onyx (any operating system): This tutorial uses the Power User view. You can change the Plesk view by clicking on ‘Change View’ at the bottom of the left column.
  • Firewall access: If you have a firewall, you need to allow access on port 443 to enable secure HTTPS traffic to and from your server.
