Perhaps the links in the site do not point to the proper
location. With a config as simple as yours, the problem is either in
the app or in the backend configuration. You have no root defined so
Nginx is trying the open the files with the default root:

/usr/local/nginx/html

I suggest you enable the debug log and trace the request:
