Hello,
NGINX has as document root the folder /usr/share/nginx/html/. To change your folder edit /etc/nginx/sites-available/default and set root to /var/www/html. I think you will need to create by your self the folder with sudo mkdir -p /var/www/html
I made the folder, but now ssh account can't upload to the server.
Error Directory /var/www: permission denied
You need to allow your ssh user to write to /var/www. Run the following command as root:
sudo chown -R user:user /var/www
Installed LEMP with ubuntu 14.04.
Created the /var/www folder
Allow my ssh user to write to /var/www
Uploaded everything, but now I'm getting 403 Forbidden
