trying to get my downloads folder

I have NGINX installed on a VPN and I would like to access the "downloads" folder via https. I followed instructions given to me as follows:

Now, in order to download your files from your vpn, you will move the download folder of deluge into nginx www folder. For example: downloads folder (/usr/share/nginx/www/downloads). Your files will be accessible at http://ip-address/downloads.

Change the configuration file is at /etc/nginx/sites-available/default to allow the downloads folder to be accessable via https.

Edit that file and you will see a line like root /path/to/root/folder/here <-- change this to your download location.

In that file I replaced

root /usr/share/nginx/html;
index index.html index.htm;

with

root /usr/share/nginx/www/downloads

Then he said I had to:

You also need to enable autoindex. By default, nginx will not list the files inside a folder (security reason).

Add these lines:

autoindex on;
autoindex_exact_size off;
autoindex_localtime on;

Which I did.

So far I cannot access the downloads folder and thought I would look for some help here.

Thanks very much
