Hello, @brokercl

What you can do in order to achieve this is to set a Nginx reverse proxy. You can do this by editing the nginx configuration file:

open/create the config file /etc/nginx/sites-available/domain.com

You should have the following content:

server {
  listen 80;
  server_name domain.com;

  location / {
   proxy_pass http://localhost:9000;
  }
}

You need to create the symlink for the file and make it available in the sites-enabled directory as well:

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

Then check the Nginx configuration files for any syntax errors:

sudo nginx -t

If you see that the Syntax is Okay, then restart Nginx. If you get some syntax errors, check the exact row/line that was reported in the message and sort this out before you continue further.
