Unable to connect to the server

General Discussions microk8s

Hi,
I’m using Windows 10 Enterprise and I just installed Microk8s. It seems installation completed without any error. But if I want to check K8S status like below, it gives error;

C:\Windows\system32>microk8s kubectl get all --all-namespaces
Unable to connect to the server: dial tcp 10.0.2.15:16443: 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 idea how can I solve this?

Thanks!

Try to see what this output shows

microk8s status

My hunch is that its not yet up.

Looks good to me. Running the command microk8s get no is still failing?

Yes, unfortunately still same error

I am encountering the exact same error. Windows 11 Pro. If I sign into the VM and run sudo microk8s.kubectl everything works as expected. This happens after a Windows forced restart (I really do hate Windows). The only solution that I have yet found is to uninstall than reinstall Microk8s.

I see what it is.

When I run the microk8s kubectl config view --raw in Windows, the IP address is wrong. For example, in my case, the config shows https://172.26.23.109:16443. But when I run multipass info --all the correct IP is 172.26.208.178. The correct IP is shown after running microk8s config, though, so it appears that Microk8s is failing to update its kubectl config.

I was able to fix it with microk8s kubectl config set-cluster microk8s-cluster --server="https://172.26.208.178:16443".
