QRadar: Applications fail to load with error "404 page not found' due to lack of connectivity

Troubleshooting


Problem

A QRadar App Host is a managed host that is dedicated to running apps. As any other managed host in the deployment, QRadar App Hosts require connectivity to the required services and ports running on the Console.
When a connection to a required port is needed by an application, and the connection fails, it can affect the application load.

Symptom

The administrator can verify whether an app is not working in the user interface (showing 404 page not found).
