Detailed description of the issue:

A container running blinkt-k8s-controller was unable to access the kubernetes API server on 10.96.0.1.

This was caused by a incorrect pod-network-cidr in roles/master/tasks/main.yml. The correct pod-network-cidr for flannel is 10.244.0.0/16.

I'm not sure where you're getting 10.96.0.1 from. The podnet variable is set to 10.244.0.0/16: https://github.com/rak8s/rak8s/blob/9031d74fea51ba15d9c91d529eca230ebc59ab0b/group_vars/all.yml#L2

Please look in roles/master/tasks/main.yml. The kubeadm init command doesn't use the podnet variable.
