my first EKS - error: You must be logged in to the server (Unauthorized)

Question

I've seen this error in many previous questions, but as a complete beginner I'm not sure if those questions were relevant to my situation.

1. I've created a cluster called wiz_try using the AWS EKS gui. When it asked for a role, I've created a new one with EKS policy AmazonEKSClusterPolicy.

2. I've download AWS ICL and configured it. Also downloaded Kubectl.

3. checked that I see the cluster:

aws eks --region eu-central-1 describe-cluster --name wiz_try --query cluster.status

ACTIVE

4. ran

aws eks update-kubeconfig --name wiz_try --region eu-central-1

this has created a config file:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: *******
    server: https://***.gr7.eu-central-1.eks.amazonaws.com

      args:
      - --region
      - eu-central-1
      - eks
      - get-token
      - --cluster-name
      - wiz_try
      command: aws

kubectl get svc error: You must be logged in to the server (Unauthorized)

I tried solving by running aws eks update-kubeconfig --name wiz_try --region eu-central-1 --role-arn arn:aws:iam::***:role/EKS_cluster_role

as this is the role I created, but this is not helping.

what am I missing?

Thanks
