Nginx overriding the default server - nginx

Question

I am trying to serve a webpy application under Nginx on debian linux (RasPi).
I can successfully serve the webpy app if I use any port other than 80. But If I try to use port 80, it is not possible to hit my webpy app, I will always see instead the default "Welcome to Nginx" page.
I have tried everything I can think of the disable the default page and override it with my webpy app but nothing seems to work. I have deleted the default link, and file out of their respective directories. I have tried pointing directly to sites-enabled/webpy rather than sites-enabled/* in nginx.conf. Still result is always the same, if I hit http://[ip-address]/ I will see the welcome to nginx page.
I have tried several times nginx -s reload and stopping/starting everything. And rebooting the device.
How do I override this so that it is serving my webpy app on port 80?
nginx.conf
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
events {

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*; # I even tried pointing directly to webpy instead of *
}
#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
# server {
# listen localhost:110;
# protocol pop3;
# proxy on;
# }
#
# server {
# listen localhost:143;
# protocol imap;
# proxy on;
# }
#}
As far as I can tell this should make any thing inside of sites-enabled/ get served
I have only 1 thing inside of sites-enabled/
$ ls -la
total 8
drwxr-xr-x 2 root root 4096 May 31 17:49 .
drwxr-xr-x 6 root root 4096 May 31 18:08 ..
lrwxrwxrwx 1 root root 32 May 31 17:49 webpy -> /etc/nginx/sites-available/webpy
which is a link to sites-available/webpy
# webpy server
server{
listen 80; # if I set this to 8080 then I can hit the app on that port.
location / {
fastcgi_param REQUEST_METHOD $request_method;

}
location /static/ {
root /path/to/www;
if (-f $request_filename) {
rewrite ^/static/(.*)$ /static/$1 break;
}
}
}
I don't have any other files, or links inside of sites-enabled/ or sites-avaialbe/ I removed the default ones from these folders.

When you set
listen 8080;
run
sudo netstat -tlnp | grep nginx
and see what ports nginx is listening on. It should not be listening on port 80 at this point. If it is try
sudo grep -rnIw "80" /etc/nginx
If nginx is listening on port 80, there must be a declaration for it somewhere under /etc/nginx
As a sanity check, I would also stop the nginx server completely
sudo service nginx stop
and see if some other server is serving the default nginx page.
