Hello, @SephiaSky

I’ve followed the tutorial on a fresh droplet and everything went all good without any issues. Do you get any syntax errors when you check the Nginx configuration using the command you’ve mentioned:

sudo nginx -t

You can skip the part with the creation of the site’s files, e.g the HTML file for the index page and go and setup directly the server block:

/etc/nginx/sites-available/example.com

server {
        listen 80;
        listen [::]:80;

        root /var/www/example.com/html;
        index index.html index.htm index.nginx-debian.html;

        server_name example.com www.example.com;

        location / {
                try_files $uri $uri/ =404;
        }
}

then enable the file by creating the symlink

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

and then tweaking the nginx config file:

/etc/nginx/nginx.conf

Let me know if you have any questions.

Regards,
Alex
