On the form that pops up, push Add in the Panel address section.
Complete the New Address form:
IP Address – Specify the IP address where the incoming connections will be received;
Port – Specify the port number to be used for incoming connections. The default setting will be used if you leave this field blank;
Forbid HTTP connections – The built-in web server can handle both HTTP and HTTPS queries. Check the check-box if you wish to prohibit HTTP queries. If you do this, they will be automatically redirected to HTTPS;
The address you have created will be added to Panel address.
Access to panel may be lost if the port is changed. Before you do the change, go to the system Firewall Rules and open the port you wish to assign to the panel.
Port 80 is the default port of the HTTP protocol. Port 443 is the default port of the HTTPS protocol. To prohibit HTTP connections for port 443, you need to set up port 80. If you enable the Prohibit HTTP Connections option for port 80, then every time an HTTP connection is requested at port 80, the query will redirect to port 443 via HTTPS. Keep in mind that HTTP connections are prohibited for port 443.
