Found out that by checking the kubectl config kubectl config view   The clusters part was null, instead of having something similar to - cluster: certificate-authority-data: DATA+OMITTED server: https://kubernetes.docker.internal:6443 name: docker-desktop   It was not parsed because of time differences between my machine and a server (several seconds was enough). Running sudo apt-get install ntp sudo apt-get install ntpdate sudo ntpdate ntp.ubuntu.com   Had solved the issue.
