I am new to rancher. I am having an issue setting up EKS cluster with rancher server. I am creating the EKS cluster from the rancher server UI, which is running on an EC2 instance, accessing via an ALB. Cluster is shown as created in AWS console, but stuck in "Waiting for API to be available" in rancher UI. Also seeing '[Disconnected] Cluster agent is not connected' message. Only have public access configured for the API Server endpoint. Additionally, I am deploying the EKS cluster in the same VPC/subnet the rancher server instance is deployed in. Any ideas?
