QRadar: High Availability appliance is in Unknown state, 'Sent update status of host to unknown'

Troubleshooting


Problem

Administrators who experience issues where the high availability (HA) displays 'Unknown' in the user interface from the Console. The unknown state of the standby appliance can be confirmed with the HA state command. If the primary appliance cannot connect to the secondary appliances due to a missing SSH key, the following error is displayed: Sent update status of host xx.xx.xx.xx to UNKNOWN.

Symptom

The System and License management interface from the Admin tab can displays the Host Status column as 'Unknown'. 

The logs on the active HA appliance can display the following INFO message in /var/log/qradar.log.
  [hostcontext.hostcontext] [Server Host Status Processor] com.q1labs.configservices.controller.ServerHostStatusUpdater:   [INFO] [NOT:0000006000][X.X.0.97/- -] [-/- -]Sent update status of host 192.168.0.98 to UNKNOWN
