When you just installed the UniFi controller and navigate to the web interface, you will get a notification that “Your connection is not private”.

In this tutorial, we will change self-signed certificate with a certificate issued by a Certificate Authority.

This tutorial will show you how to install a UniFi controller on Ubuntu. First we will configure the firewall using ufw and secure our server before installing UniFi. For this example, we are using Ubuntu 16.04 but there is nothing stopping you from applying it to a newer version.
