The directory index error you're seeing is most likely the result of a missing index ...; directive in your server block or the nginx.conf file. The index directive needs to match the language that you're serving.

For example, if I were serving a WordPress site, I'd want to have something such as:

server {
    listen 80;
    server_name domain.com www.domain.com;

    root /path/to/public_html;

    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        ...
        ...
        ...
    }
}

While the above is not a complete example, it shows where the index directive may be placed to help prevent that error. You can also modify the index directive in /etc/nginx/nginx.conf under the http block and add it there.

Under http it's global, thus affects all server blocks and will help redundancies.
