SHOUTcast doesn’t support SSL/HTTPS. The Shoutcast service on the port like 8000 is an unencrypted server for HTTP and ICY. So Shoutcast need proxy/restream HTTP stream to HTTPS.

You can use PHP or NodeJS or NGINX to restream Radio Streams.

Re-Stream PHP Proxy file – stream/index.php

Icecast / Shoutcast MP3 Radio Stream 
Shoutcast V1 (//shoutcast-server-ip:port/) 
Shoutcast V2 (//shoutcast-server-ip:port/streamname) 
Icecast V2 (//icecast-server-ip:port/streamname)
Type: Audio
Codec: MPEG Audio layer 1/2 (mpga)
Channels: Stereo
Sample rate: 44100 Hz
Bitrate: 128 kb/s
header('Content-Type: audio/mpeg');
$server = "[Server-IP-Address]";
$port = "[Port]";
$mount = "[Mount-Point]";
// HTTP Radio Stream URL with Mount Point
$url = "//".$server.":".$port."/".$mount;
// Open Radio Stream URL
// Make Sure Radio Stream [Port] must be open / allow in this script hosting server firewall 
// Read chunks maximum number of bytes to read
if(!$f) exit;
echo fread($f,128);  

.htaccess – stream/.htaccess

<FilesMatch "mp3$">
    SetHandler application/x-httpd-php5

RewriteEngine On
#RewriteBase /
# Redirect MP3 to PHP
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*).mp3$ index.php [L]

So if you host these files on HTTPS enabled server in folder “stream” …. Radio Stream Proxy URL will look like
