Hi all. I have created downstream cluster ( EKS provider v1.21, Rancher local cluster v2.6.3). For some reason it stucks on

Waiting for API to be available

, in conditions there are

Cluster agent is not connected

event. At the same time AWS console shows that EKS cluster is in

Active

, so basically it means that EKS cluster is running and ready to use. What can the reason of this issue? I understand that

Waiting for API to be available

is to generic issue, but I have no idea where I need to look for the problem. The interesting thing that there is no rancher agents on any of worker nodes. Rancher is accessible from downstream nodes, so connection shouldn’t be an issue here.

Security group issue maybe ?
