Error starting filebeat as daemonset in kubernetes

I run filebeat as a kubernetes daemonset in kubernetes cluster with autodiscover turned on and I have a errors in filebeat log:

"ERROR   kubernetes/util.go:90   kubernetes: Querying for pod failed with error: performing request: Get https://10.96.0.1:443/api/v1/namespaces/default/pods/filebeat-daemon-7nkqt: dial tcp 10.96.0.1:443: connect: connection refused
ERROR   kubernetes/watcher.go:183       kubernetes: Performing a resource sync err performing request: Get https://10.96.0.1:443/api/v1/pods?fieldSelector=spec.nodeName%3Dlocalhost&resourceVersion=0:
dial tcp 10.96.0.1:443: connect: connection refused for *v1.PodList".

When I add a command "sleep 5" into filebeat start command line, errors disappear. Does anyone have a solution for this problem?

Here is a filebeat manifest:
