The custom /radio/stream-player/ page is served over HTTPS, so the browser
still applies mixed-content restrictions and upgrades http:// audio to https://,
which fails for streams without TLS support.
Fix: window.open(url, '_blank') navigates the tab directly to the HTTP URL.
The tab itself is then HTTP, bypassing mixed-content restrictions entirely.
Browser plays the stream natively with its built-in audio player.
