How to make Nginx redirect to 404 if subdomain doesn’t exist in localhost domain

Question

This is my localhost server configuration for Nginx. This is at /etc/nginx/sites-enabled/development/localhost

server {
    listen 80 default_server;
    server_name localhost;
    root /var/www/html;
    index index.nginx-debian.html;

    location / {
      internal;
    }

    error_page 404 /404.html;
    location /404.html {
      root /var/www/html/errors;
      internal;
    }

}

If I call http://locahost in URL bar, a 404 page error is shown. But should show index.nginx-debian.html. But if I call http://localhost with a valid subdomain, it works. Like that http://users.localhost, defined in /etc/nginx/sites-enabled/development/users.

I want to show Nginx default page if I only call http://localhost, 404.html if subdomain doesn’t exist, and another any page if I call http://localhost correctly with a defined subdomain.

I solved as follow.

At /etc/nginx/sites-enabled/development/default.

server {
  listen 80 default_server;
  server_name *.localhost *.<host-name>;
  root /var/www/html/errors/404;

  location / {
    index subdomain.html;
  }

}

At /etc/nginx/sites-enabled/development/localhost.

server {
    listen 80;
    server_name = localhost;
    root /var/www/html;
    index index.nginx-debian.html;

    # to URI errors caused by paths after domain
    error_page 404 /domain.html;
    location = /domain.html {
        root /var/www/html/errors/404;
        internal;
    }
}

I don’t know if this solution is the best, so if someone has a better solution, post here. Thanks.
