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

    location / {
        proxy_pass http://localhost:3000; # or the port where your Next.js app is running
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

1. Save the Nginx configuration file and restart Nginx by running the command sudo service nginx restart.
2. Test accessing your Next.js app using your custom domain in a web browser. It should now be accessible with your custom domain.
