In this video I’ll explain how to add a free SSL Certificate for web traffic in Plesk Onyx.
First we’ll enable the Let’s Encrypt extension in Plesk, then we’ll create the certificate and prepare our subscription for SSL traffic. And finally, we’ll tweak two values in the WordPress database so that all requests will be directed to https rather than http.
Note that Let’s Encrypt SSL Certificates can only be used to encrypt web traffic between your server and a client’s browser. They cannot currently be used to secure email or Plesk itself (but who knows what the future holds).
