I have a web application that communicates with Amazon's Alexa API and is hosted locally on a computer. The application must use https for the communication and is accessed by using the IP address. The problem is that whenever I access the application I get the "The connection is not private".
I've looked into getting a certificate from places like LetsEncrypt, but they require that a domain is present, which in my case I only have a local IP address.
Is there a way to obtain a certificate for this application so that there's no error? I wwill also have to distribute this application to clients, so the certificate must be either portable or easily renewable.
