Hi Vasanthan,
You have to configure the "host" to pod's IP as follow,
deployment.config:
type: ha
eventSyncServer:
host: ${NODE_IP}
here the "NODE_IP" is an environment variable and you can define it in the
Kubernetes deployment yaml as the pod's IP. Otherwise, the active node and
the passive node cannot identify each other's IP. Please find a similar
configuration here[1].

Thanks,
Thilina.
