NGINX giving 404's, never proxy passes to fastcgi-mono-server4

Question

Working on getting a skeleton of ASP.Net application running on Ubuntu. Installed all the requisite applications. Just trying to serve index.html or index.aspx to start. However, running through Nginx never seems to get through the proxy, always get a 404 from Nginx itself.

Starting mono server as:

fastcgi-mono-server4 /loglevels=All /printlog /verbose /applications=/:/opt/esoa /socket=tcp:127.0.0.1:9000

Nginx configuration:

server {
            listen 80;
            server_name _;

            location / {
                    root /opt/esoa;

                    index index.html;
                    access_log /var/log/nginx/esoa.log;

                    fastcgi_param SERVER_NAME $host;
                    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                    fastcgi_param PATH_INFO "";

                    fastcgi_pass 127.0.0.1:9000;
                    include /etc/nginx/fastcgi_params;
            }
    }

Output from Mono server when it starts:

Simple wget never shows traffic to Mono server:

Answer 1

Duh, there was another server entry in the nginx.conf that seemed to cancel mine out.
