I setup my network load balancer and target group. I associated master node private IP from my running instance to this new target group and registered there.
It started with the 'initial' status and then after 5 mins, it turns to 'unhealthy' status. I am not able to find out why 'Health checks failed'. What stop the health check to be successful?
I am using AWS GUI, not too much familiar with CLI. pls assist.
More Info---
Health check settings are: Protocol = HTTP Path = / rest all defaults
Target group as follows: Target type = ip Protocol : Port = TCP : 8998
master node private IP is within the vpc and subnet
Based on the comments.
The issue was with incorrectly set security groups on the instances.
The solution was to allow incoming traffic from the security group of the load balancer.
