Silently fails to run on port 443 about icecast-server HOT 1 OPEN

This sounds like your operating system (I guess you are using a linux as you use the linux PRNG profile) refuses Icecast to bind to that port because it's a privileged port.

If that's the case it really depends on your operating system how to get this working. You could try to set the permissions for Icecast to bind to that port anyway (for Linux see capabilities(7)), start the process as root and do a change user later (per Icecast config; this is something I would avoid), or use a network level redirect (iptables target REDIRECT, see iptables-extensions(8)). There might be more options.

Using a reverse proxy is not recommended as they tend to break things (but often seem to work at initial testing) and are super hard to correctly configure for this usecase.

If this problem is not a permission problem it would be very nice if you could open a ticket in the official ticket system.
