This is your issue looks likes.

1. **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.
`
2. Update Your EKS Cluster and Region and check your config file with following commands:

`aws eks --region  describe-cluster --name  --query cluster.status`

`aws eks --region  update-kubeconfig --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
