I’ve installed plexamp v4.12.4, it shows up as a player from my phone, but there’s no playback possible. Then i go to the webui of the player, visible through a reverse proxy at, let’s say, https://plexamp.local.network (reverse proxy behind split-horizon DNS), pressing “Play” and no playback still. Going to network tab of developer tools I see that browser is trying to access the private IP (http://172.1.2.3:32500/resources) and not the https://plexamp.local.network/resources, which is available on the network. Shared detailed client/server logs and network setup to support@ and security@.

Not saying it’s not right or wrong, but I am curious, why are you trying to connect to a local resource via a reverse proxy? Plexamp is not going to advertise your remote proxy URL (that’s only possible for servers).
Are your phone and Plexamp headless devices on the same network? Or are you using VLANs and splitting the devices onto separate logical networks?
Also, you don’t need to obfuscate RFC-1918 IP addresses; no one can connect to your devices on non-routable addresses.
Those are definitely separate /16 networks for the host connected to speakers and phones/laptops. I don’t want to expose more ports on the host other than those already open.
src/index.js seems to have only one place where IP/port are determined, so I don’t see any significant changes required when original sources are available.
I just want my Linux box with speakers connected to play my FLACs. I have originally tried chromecast, but it hardcodes Google DNS servers and forces resolution through them, which doesn’t work with any split-hirizon setups. Then I tried AirPlay receiver within PulseAudio, but I could only get ALSA running. Then I used spotifyd for two years, but it started experiencing port binding issues a lot recently, rendering it unusable and I can’t play audio anymore from my Linux server box with speakers connected 
I’m limited by the number of power sockets in the cabinet, so I’m exploring all options before throwing in more hardware devices.
