How to add an SSL certificate for a home server?

Question

Apache HTTP Server

There is a site on a home server that is hidden behind Cloudflare. Everything works over HTTPS, certificates are issued by Cloudflare itself.
But there is an audio player on the site:

<audio >
  <source src="http://192.168.0.100:8000/audio" >
</audio>

Because of which the content of the site is considered insecure (because HTTP).
I'm trying to encrypt the source, for this I use SSL certificates issued by Cloudflare on my server, in the end my player looks like this:

<audio >
  <source src="https://192.168.0.100:8000/audio" >
</audio>

But the browser still considers this certificate invalid and the player does not start. On the server side, this is the error:

Failed to accept new client: SSL accept() error: error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown

What is the reason? Is it possible in principle to use SSL certificates from Cloudflare in this way? And if not, how do I get a valid certificate if my server is not directly related to my domain?
Audio is generated using Liquidsoap, which can create https sources.

Answer 1

The error is due to the fact that you are trying to connect via HTTPS on port 8000, where there is most likely no SSL.
