Icecast2 running under nginx not able to connect

I want to start saying that I've looked all over the place to find an answer to this problem and it just seems like either nobody else ran into this problem or nobody is doing it. So, I recently install icecast2 on my Debian server, The thing is that I'm completely able to broadcast to my server from my local network connecting to its local IP on port 8000 and hear the stream over the internet on radio.example.com since I proxy it with nginx, so far no problems at all. The problem lies when I want to broadcast to the domain I gave with nginx stream.example.com

I have two theories, one is that the proxy is not giving the source IP to icecast so it thinks it's beign broadcasted from 127.0.0.1 and the other is that nginx is doing something strange with the data stream and thus not delivering the correct format to icecast.

Any thoughts? Thanks in advance!

Here is the nginx config

server {
    listen 80;
    listen [::]:80;
    server_name radio.example.com;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Real-IP $remote_addr;


    location / {
            proxy_pass http://127.0.0.1:8000/radio;
            subs_filter_types application/xspf+xml audio/x-mpegurl audio/x-vclt text/css text/html text/xml;
            subs_filter ':80/' '/' gi;
            subs_filter '@localhost' '@stream.example.com' gi;
            subs_filter 'localhost' $host gi;
            subs_filter 'Mount Point ' $host gi;
    }
}

server {
    listen 80;
    listen [::]:80;
    server_name stream.example.com;

    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Real-IP $remote_addr;
    location / {
            proxy_pass http://localhost:8000/;
            subs_filter_types application/xspf+xml audio/x-mpegurl audio/x-vclt text/css text/html text/xml;
            subs_filter ':8000/' ':80/' gi;
            subs_filter '@localhost' '@stream.example.com' gi;
            subs_filter 'localhost' $host gi;
            subs_filter 'Mount Point ' $host gi;
    }
}

And this is what I get on icecast error.log

[2018-08-10  14:15:45] INFO source/get_next_buffer End of Stream /radio
[2018-08-10  14:15:45] INFO source/source_shutdown Source from 127.0.0.1 at "/radioitavya" exiting
Solution

  • tl;dr - Don't reverse proxy Icecast.

    Icecast for various reasons is better not reverse proxied. It is a purpose built HTTP server and generic HTTP servers tend to have significant issues with the intricacies of continuous HTTP streaming.

    This has been repeatedly answered. People like to try anyway and invariably fail in various ways.
