• Kubernetes version (use kubectl version):

• Cloud provider or hardware configuration: 4 Raspberry Pis connected with ethernet but wlan doesn''t change it. The master has the static ip 10.0.0.1 and the nodes have 10.0.0.201 - 10.0.0.203
• OS (e.g. from /etc/os-release): HypriotOS, but it neither works with Raspbian

What happened?

After successfully executing sudo kubeadm init --pod-network-cidr=10.0.0.200/28 --apiserver-advertise-address=10.0.0.1 on the master node, I can't join the other nodes because of: Failed to connect to API Server "10.0.0.1:6443": token id "wpiklq" is invalid for this cluster or it has expired. Use "kubeadm token create" on the master node to creating a new valid token
I tried generating a new token, but that didn't change anything. Also I'm able to communicate between the nodes on the port 6443.(I tested the port with netcat)

What you expected to happen?

I expected that the node would join the cluster.

How to reproduce it (as minimally and precisely as possible)?

Download HypriotOS and flash it to a SD card.
Add the repo and install kubeadm.
Create a cluster on the master node.
Try to connect from the client.

Anything else we need to know?

Don't think so.

Edit: My issue is basically the same as #1108, but The reason was 'Controller: Invalid --cluster-cidr, mask size of cluster CIDR must be less than --node-cidr-mask-size' didn't help me that much. (Also i tried to generate a token with ttl=0)

Sorry, just reread the documentation and found out that --pod-network-cidr shouldn't point to the "real" IP addresses of the nodes, but rather it should be a range, where the virtual network is. And I guess that connections from the internal network shouldn't be accepted.
(Also I think it should be documented more clearly, because I only found this information in "Installing a pod network add-on" under the flannel tab.)
