Control Module returns error 500

[vanlueckn]

I have this nginx rtmp config. Requests to the control module with curl are returning error 500. Goal of my config is to show a static image if stream is offline.

My nginx.conf:

user www-data;
worker_processes 1;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
error_log /var/log/nginx/error_log info;

events {
        worker_connections 1024;
        use epoll;
}

http {
        include /etc/nginx/mime.types;
        default_type application/octet-stream;
        log_format main
                '$remote_addr - $remote_user [$time_local] '
                '"$request" $status $bytes_sent '
                '"$http_referer" "$http_user_agent" '
                '"$gzip_ratio"';

        ignore_invalid_headers on;

        server {
                listen 80;
                server_name stream;

                access_log /var/log/nginx/stream.access_log main;
                error_log /var/log/nginx/stream.error_log info;

                root /var/www/stream;

                location /control {
                        rtmp_control all;
                }
        }
}
