Hola Felipe,
Have you followed these instructions when installing your Guardium appliances:
https://www.ibm.com/docs/en/gdp/12.x?topic=installing-your-guardium-system
If the appliance is running, but you cannot access via web, it could be that the web server (tomcat) is not running or network ports are getting blocked on the network. Try the cli command:
restart gui
and review these instructions

Saludos,
Marcio
