I am new to Kubernetes. I built three nodes and then realized that I messed up and deleted them. Now when I attempt to add new nodes, I cant because it keeps complaining about the nodes I have already deleted. When I attempt to delete them manually I keep getting:

kubectl delete node ks01
Unable to connect to the server: dial tcp 10.21.30.165:6443: connect:network is unreachable

How can forcefully delete the nodes or clean up the cluster to be able to start over?

Try these steps

1. First Mark the Node as unschedulable to prevent new pods from being assigned to it:

kubectl cordon <node_ID>
kubectl drain <node_ID>

2. Then try to delete it

kubectl delete node <node_ID>

I went ahead and removed the .kube/config file and then started over. This seemed to have worked for me.
