[ERROR] [controlPlane] Failed to upgrade Control Plane: [[host rancher-w1 not ready]]

Hi everybody, I have set-up a Rancher Server from which I am trying to create a new cluster.
I have 2 VMs where both have been set-up to work as etcd, control plane and worker

Provisioning log is reporting the following
