Nginx rtmp module hls being created but not available?

Question

Nginx

NGINX CONF:

worker_processes  1;
events {
    worker_connections  1024;
}


rtmp {
    server {
        listen 1935;
        application live {
            live on;
            interleave on;

            hls on;
            hls_path /stream/hls;
            hls_fragment 15s;
        }
    }
}

http {
    default_type application/octet-stream;
    add_header 'Access-Control-Allow-Origin' '*' always;
    add_header 'Access-Control-Expose-Headers' 'Content-Length';
    server {
        listen 80;
        location /tv {
            root /stream/hls;
        }
    }

    types {
        application/vnd.apple.mpegurl m3u8;
        video/mp2t ts;
        text/html html;
    }
}

hls files are created but do not work in players using ffmpeg
