I have a kubernete server running for months on AWS installed with kops 1.11.0.

I do not know why when I am running a kubectl command to my server from my deploy pipeline or my local computer I have

Unable to connect to the server: EOF

All my services seems to work well

The read operations are on the master

nodes versions: 1.11.7 master version: 1.11.6

I can ssh into my master but no idea of command I can run to help

The cluster is running since five monthes without problems and since two days I have the issue.

On my elb view, the master ec2 instance is OutOfService

@xfangfang yes my api container was down on the master,

I did not restore it the good way, i destroyed everything trying to restore it, if something can give us the good practice

Running docker ps on my master I has 0 containers running
