Hi there @bittu,

You would just need to add another Nginx server block for the other subdomains, for exmaple, let’s say that you have your wildcard server block at:

/etc/nginx/sites-enabled/wildcard_example.com

And it has the following content:

server {
    listen 80;
    server_name *.example.com;

    location = / {
        proxy_pass http://demo-server:4000/sites/fivespan/;

    }


   location ~ /(.*) {
      proxy_pass  http://demo-server:4000/$1;
    }
}

Now the next thing that you need to do is create another server block, you can do that by adding another file in your sites-available folder and then creating a symlink to your sites-enabled folder as described here.

Then the new file that you have would be available at: /etc/nginx/sites-enabled/admin.example.com, and it would have the following content:

server {
    listen 80;
    server_name admin.example.com;
    root /var/www/html;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }
}

This way you will have your wildcard server block but also have a separate server block for any specific subdomain name that you would like to be excluded from the wildcard.

Hope that this helps!
