请问怎么解决的，我遇到一样的问题了

edit /etc/kubernetes/manifests/kube-apiserver.yaml
--insecuret-port=8080
--insecure-bind-address=0.0.0.0
restart

the quickesty way, i think； file: examples/kubeedge-counter-demo/web-controller-app/utils/kubeclient.go should be edit like this

// replace this with the K8s Master IP
var KubeMaster = "https://192.68.105.207:6443"
var Kubeconfig = "/static/admin.conf"

and copy admin.conf to your container；fileexamples/kubeedge-counter-demo/web-controller-app/Dockerfile add line

COPY admin.conf /static 

the better way is get permission by clusterrole && clusterrolebinding && serviceaccount，and also i think this demo has a better way to update CR，if i will solve those problems，i will share it

maybe you should check deployment，hostNetwork: true i delete it and didn`t get error
