In continuation of the previous reverse proxy solution, here its using apache2 in /etc/apache2/sites-available/kewrunner.com.conf (for example).

<VirtualHost *:80>
        ServerName kewrunner.com
        ServerAlias www.kewrunner.com
        ServerAdmin webmaster@kewrunner.com
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        ProxyRequests Off
        <Proxy *>
          Order deny,allow
          Allow from all
        </Proxy>
        
        ProxyPass / http://127.0.0.1:8090/
        ProxyPassReverse / http://127.0.0.1:8090/

        <Location />
          Order allow,deny
          Allow from all
        </Location>

   </VirtualHost>

Remember to enable reverse proxy module into apache2 and restart it.

sudo a2enmod proxy
sudo a2enmod proxy_http
sudo systemctl restart apache2.service
