Nginx 404 while accessing app

[AjaySawant]

Hey, I also would like to mention you that it works if I create a symbolic
link of html folder inside /etc/nginx directory which points to
/usr/share/nginx/html directory. The only concern is why is it picking up
from /etc/nginx/html directory even though I did not mention anything about
that directory in my config.
