I have running k8s cluster using kops. the autoscaling policy terminate the master machine and recreated a new one since then every time i try to run kubectl command it returns "The connection to the server refused, did you specify the right host or port". i tried to ssh to the master machine but the did not found any of k8s services so i think the autoscale policy did not configure the master node correctly. so what should i do in this situation ? update: also i found this log in syslog file:
E: Package 'ebtables' has no installation candidate

sudo apt-get -o Acquire::Check-Valid-Until=false update
sudo apt-get install -y ebtables --allow-unauthenticated
sudo apt-get install --yes conntrackand everything is running fine now
