It is hard to tell exactly what might went wrong here but there are few things that you could do in order to fix your issue:

.kube/config is missing or not configured correctly. Create or copy a valid kubeconfig file to solve this.
You have swap not turned off. With swap enabled, kubelet service will not start. Execute: sudo swapoff -a in order to make sure it is disabled.
kubelet might be down. Check kubelet logs and make sure that kube-apiserver is up and running.
Check which ports are appropriate to use with the telnet command.
