I have created a Amazon Elastic Kubernetes Service in US East (Ohio)us-east-2 region. After cluster setup I have created Fargate profile which is done successfully. Now I am trying to Add a Node group but its ends with showing error "NodeCreationFailure Unhealthy nodes in the kubernetes cluster" issue. What can be the possible reason??

your nodes are unable to register with your Amazon EKS cluster.
A quick and dirty solution consists in adding AmazonEKS_CNI_Policy to the worker nodegroup role.
If that's solve the problem please be aware that the recommended approach is instead: https://docs.aws.amazon.com/eks/latest/userguide/cni-iam-role.html
