Help me point domain to my droplet

Hello,

I bought a domain (sjearthquakes.app) from GoDaddy, created a Droplet in DigitalOcean. I have prescribed NameServers for GoDaddy:

• ns1.digitalocean.com
• ns2.digitalocean.com
• ns3.digitalocean.com

In DigitalOcean, in the Networking -> Domains section, I added this domain for my droplet.

It has been more than 12 hours since I set all the settings.

In the droplet itself, I have Ubuntu 22.10 x64 spinning, inside of which nginx and also my NodeJS server are running.

If I contact directly by the IP address of the Droplet my server on Node JS works out as it should. But if you use the domain name, nothing happens (“We can’t connect to the server at sjearthquakes.app.”).

Here is my nginx setup file:

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

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name sjearthquakes.app www.sjearthquakes.app;

        location / {
                proxy_pass http://localhost:3000;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
        }
}

Please, help me to identify the issue.
