Hello,

I’m fairly new to Scylla. I’m trying to install it on an EKS cluster so my devs can load data into it. I’ve installed the cert-manager and scylla operator with helm and they’re running without any issues. When i try to install Scylla, i’m getting following error.

My EKS cluster is private but it has a NAT gateway and has access to the internet. My EKS node group allows Ingress from EKS cluster on tcp ports 443,9443,6443,4443,10250,8443. Can someone please advise the issue here?

Probably you’re missing a rule allowing traffic from Kubernetes master nodes to worker nodes on 443 port.
