I am a bit new in the IBM QRadar SIEM product and my question may be silly. Unlike other IBM security solutions, QRadar does not seem to have any command line interface to perform some troubleshooting steps. From time to time, the browser seems to lose connection to the appliance. Afterwards, I cannot seem to reconnect it, I have to restart the appliance which is inconvenient. Is there a way to manually reset the connection of the browser? How do I determine the port being used by the UI.
