Hi @anandkumar1427,
The health checks seem to fail because the health check port does not accept the connection. This is typical for a firewall blocking access to that particular port.
What type of infrastructure is hosting your cluster? Local hypervisor or cloud? In each case please ensure that the infrastructure level firewall allows all incoming traffic from all sources, all protocols, to all ports. In addition, the guest OS of your VM instances should have firewalls disabled.
Regards,

Thanks
Able to proceed now.
I am using GCP (e2-standard). As per your suggestion, have updated firewall rules to allow all ports
