Unable to register node "node-name" with API server: Unauthorized

4/23/2019

I am using kubernetes 1.13.2 on bare metals (No Provider).

I already have a master and a worker node set up while ago, but now my new worker node cannot join to the cluster and receives "Unauthorized" message when it tries to register

I have renewed my token on my master, and created a new join command. But still getting "Unauthorized" response upon joining

After sending kubeadm join ... command, it times out

[patchnode] Uploading the CRI Socket information "/var/run/dockershim.sock" to the Node API object "node-name" as an annotation
[kubelet-check] Initial timeout of 40s passed.
error uploading crisocket: timed out waiting for the condition

and here is what I get in journalctl -u kubelet
