HAproxy and nginx RTMP

Question

I am trying to use HAproxy in front of an RTMP nginx server.

It does connect but it does not play the video.

I have 2 servers: one with nginx using RTMP and another one with HAproxy.

This is the HAproxy config:

listen rtmp :1935
mode tcp
 balance roundrobin
server s1 rtmp_server_ip:1935 check

I have also tried to set it to port 1936.

This is the nginx RTMP config:

rtmp
 {
    server
     {
        listen 1935;
        listen 1936 proxy_protocol;

        notify_method get;
        on_play http://127.0.0.1/vod_handler;
        application vod
        {
                play /path_to_videos/uploads/;
        }
}
   }

This is how the setup should be:

web >> haproxy >> nginx RTMP
