Rke add node failed!

After I build rancher & k8s cluster, It’s work fine.
I wanted to add worker node to cluster, I modified rancher-cluster.yml, and one woker node,

  • address:
    port: 36000
    user: tars
    role: [worker]
    …/bin/rke up --config rancher-cluster.yml

I got this error:
INFO[0031] [healthcheck] Start Healthcheck on service [kube-proxy] on host []
FATA[0081] [workerPlane] Failed to bring up Worker Plane: [Failed to verify healthcheck: Service [kube-proxy] is not healthy on host [].

does any one know how to resolve?
