Deploy Helm Chart on Private EKS Cluster with CDK

[bdudra]

Greetings,

I'm attempting to deploy a Helm chart on an EKS cluster with a private endpoint using CDK. I'm getting a connection timeout when I attempt to deploy the CDK.

I import the cluster using the following CDK:

const cluster = cdk.aws_eks.FargateCluster.fromClusterAttributes(this, 'cluster', { clusterName: kube-${env}, vpc: vpc, securityGroupIds: [eksSgId1, eksSgId2], clusterSecurityGroupId: eksSgId1, kubectlLambdaRole: cdk.aws_iam.Role.fromRoleArn(this, 'kubectl-lambda-role', kubectlLambdaRoleArn), kubectlRoleArn: kubectlRoleArn, clusterEndpoint: clusterEndpoint });

And I install using the following CDK:

const connectedServices = new cdk.aws_eks.HelmChart(this, 'connected-services-helm',{ cluster: cluster, chart: 'connected-services', release: 'connected-services', namespace: "connected-services", createNamespace: false, repository: 'private', version: '1.2.0', });

But I get the following error message:

`The stack named EksApplicationsStack failed creation, it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: Received response status [FAILED] from custom resource. Message returned: Error: b'Error: Kubernetes cluster unreachable: Get "https://private.eks.amazonaws.com/version": dial tcp xxx.xxx.xxx.xxx:443: i/o timeout\n'

Is there anything that I need to do to enable this process?
