Remote kubernetes server unreachable

Question

I tried to install kubernetes with Docker desktop. However, as soon as I type in

kubectl get nodes

I get Remote kubernetes server unreachable error.

I0217 23:42:56.224000   26220 versioner.go:56] Remote kubernetes server unreachable
Unable to connect to the server: dial tcp 172.28.112.98:6443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Any ideas on how to fix this?

Answer 1

Have you got more than one context in your kubeconfig?

You can check this with kubectl config get-contexts.

If necessary change your context to Docker Desktop Kubernetes using kubectl config use-context docker-desktop.

Is it possible that you may have tried minikube and this has left cluster/context in your .kube\config?

Configure Access to Multiple Clusters

Answer 2

go to your HOME/.kube directory and check the config file. There is a possibility that the server mentioned there is old or not reachable.

you can copy the new config file(from remote server of the other directory of tools like k3s) and add/replace it in your HOME/.kube / config file.

Answer 3

Same error message may also happen when you switch from local k8s cluster to a remote cluster that requires VPN to connect and you are not connected to VPN.
