Remotely hosted web-application using HTTPS sometimes gives "SecurityError"

When using a remotely hosted web-application using "HTTPS":

Some browsers will give a "SecurityError" if attempting to connect insecurely using web sockets.

We recommend that you install Ranger Remote with WebSocket Secure (WSS) enabled. Enabling WSS at install time will:

Install SSL certificates for the loopback address to the Microsoft Certificate Store
Install SSL certificates for the loopback address to the Firefox certificate database
Configure Ranger Remote for a WSS connection through the loopback address

The option to enable WSS in Ranger Remote is made available at install time through the installer UI or as a command line option.

See the following link:

How can I install Ranger Remote using the Command Prompt?

There is also a workaround available for Firefox. See the follow link:
