    Hi @bdkdavid,

    Thank you for all the detailed outputs attached.

    The first concern is about the node IP addresses and the pod IP addresses. If nodes are on the network, what IP addresses are used by calico for pods? I see pods on 192.168.69.a, 192,168.76.b, and 192.168.114.c subnets. I suspect that the pod IP addresses overlap the node IP addresses - which should be avoided in a cluster.

    The second concern is about the helm chart used to deploy the kubernetes-dashboard release. The name of the chart is metrics-server-3.8.2 (which deploys a metrics-server, not a kubernetes-dashboard). The chart should have been kubernetes-dashboard-.... for a kubernetes-dashboard installation. Here I'd recommend uninstalling with helm the current kubernetes-dashboard release, and use helm to install the kubernetes-dashboard from a kubernetes-dashboard chart.

    The kubernetes-dashboard chart and general installation instructions can be found at:
