Hello,
It is Very regular issue for everyone i will give solution below in easy way:
This is your issue looks likes.
- Security Groups: If you're accessing the cluster across a VPC, ensure the control plane security groups allow
inbound traffic from the peered VPC on port 443. - Update Your EKS Cluster and Region and check your config file with following commands:
aws eks --region <your region> describe-cluster --name <your cluster name> --query cluster.status
aws eks --region <your region> update-kubeconfig --name <your cluster name>
mv $HOME/.kube/config $HOME/.kube/config.old
kubectl get svc
kubectl get nodes
=> By applying above commands one by one you resolve your issue.
this is the solution for your issue after applying above commands without any error

I have tried your solution and many other ways but still cannot connect to the API server.
As far as I know, EKS Control Plane is managed by AWS. How can I get support from AWS regarding this issue?
