Every time I install Kubernetes 1.15.3 it works great, until I reboot the VM and then it no longer listens on port 6443. Swap is off. /etc/tab only contains the root volume on my Ubuntu 18.04 server VM. Note, using flannel
cat /proc/swaps

kubectl only returns refused
kubectl get nodes
The connection to the server <myip>:6443 was refused - did you specify the right host or port?

sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Any ideas? The "interweb" only tells me to check swap, but I've checked it literally 6 different ways and all indications is that it's off.
My the admin conf file copied to .kube shows the right server and right port. The API-server is just not up. Thoughts anyone?
journalctl -xeu kubelet
Note, kubernetes1 is the name of my master server.
