      we can this error message in the node esx03.rackf10.local

      Sep 04 08:02:29 c2-esx02.rackf10.local kubenswrapper[8793]: E0904 08:02:29.208979 8793 kubelet_node_status.go:94] "Unable to register node with API server" err="Post \"https://api-int.c2-raven.rackf10.local:6443/api/v1/nodes\": dial tcp 20.14.32.222:6443: connect: connection refused" node="c2-esx02.rackf10.local"

      esx03.rackf10.local is the problem. It serves the api-int VIP but it doesn't have kube-apiserver running

      Due to this all the requests to api-int will fail

      Need to figure out why kube-apiserver-pod.yaml is missing

      I am attaching journal logs and sos report of the kube-apiserver-pod.yaml missing node and mustgather report

      Description of problem:

      Sep 04 08:02:29 c2-esx02.rackf10.local kubenswrapper[8793]: E0904 08:02:29.208979    8793 kubelet_node_status.go:94] "Unable to register node with API server" err="Post \"https://api-int.c2-raven.rackf10.local:6443/api/v1/nodes\": dial tcp 20.14.32.222:6443: connect: connection refused" node="c2-esx02.rackf10.local"


To troubleshoot this error we have tried ssh into node (20.14.32.222) c2-esx03.rackf10.local node 

Executed  below command:

$ crictl ps -a |grep api

There is no kupeapi server pod was running.

I have  checked in node c2-esx03.rackf10.local noticed that etc/kubernets/manifests/kube-apiserver-pod.yaml was  missing

Need to find out the reason why kube-apiserver-pod.yaml  was missing in the node.
