How use XOJO cgi web app in Raspberry PI with https

How i made works XOJO cgi web app using https in Raspberry PI 3 b+

You would need to install Apache or another web server if you want to use a Xojo cgi web app. Using a standalone web app is a lot easier until you want https:. There is either a blog posting or a section in the docs that describes how to install the certificate, but it does not address how to get the certificate. I looked at it once and decided I didn’t really need the extra security. I looked at getting a free Let’s Encrypt certificate. They wanted a way to verify that I owned the domain and I could not figure out how to do it on the Pi without Apache. I considered moving my domain to a shared hosting site, getting the certificate, then moving it back to my Pi. But I was concerned that I would have to do that every time the certificate needed to be renewed. At the time, I did not think about opening an SFTP port in my router that would allow them to authenticate my domain. That might work.

I found to be very helpful to handle SSL as well as reverse proxy.
