on_publish, connection refuses no matter what I put in it.

[JohnB17]

I am trying to use on_publish to verify the stream key. If I forgot to provide something, go right ahead and ask.

I can curl from the host (of the server) and it works fine.
deny publish 10.49.197.1; is there so I can allow all local IPs and block the router, only local traffic is allowed.

RTMP config in nginx.conf:

rtmp {
  server {
    listen 1935;
    chunk_size 4096;
    allow publish 10.49.197.0/24;
    deny publish 10.49.197.1;
    deny publish all;

    application live {
      live on;
      record off;

      on_publish http://localhost:8080/verify;

      # Twitch - Better Platform
      #push rtmp://live.twitch.tv/app/[REDACTED];

      # YouTube - Slower than Twitch
      #push rtmp://a.rtmp.youtube.com/live2/[REDACTED];
    }
  }
}

sites-enabled/localhost:

server {
    listen 127.0.0.1:8080;
    server_name localhost;

    if ($request_method !~ ^(GET|HEAD)$) { return 403; }

    location /verify {
        allow all;
        expires off;

        set $livepass 0;
        if ($arg_livekey = "[My Nginx Stream Key]") { set $livepass 1; }
        if ($livepass = 1) { return 200; }

        return 401;
    }

}

access.log:

10.49.197.54 [19/Nov/2023:00:54:46 +0000] PUBLISH "live" "[My Nginx Stream Key]" "" - 392 292 "" "FMLE/3.0 (compatible; FMSc/1.0)" (0s)

10.49.197.54 is my PC's local IP, I am testing by broadcasting from OBS on my PC.

error.log:

It took me probably an hour to track down, but after having a similar problem, it seems like you can't on_publish with a port. Adding a location / proxy_pass to the http { server } then passing to http://localhost/proxyed worked for me.
