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: 172.16.0.7
    port: 36000
    user: tars
    role: [worker]
    then:
    …/bin/rke up --config rancher-cluster.yml

I got this error:
INFO[0031] [healthcheck] Start Healthcheck on service [kube-proxy] on host [172.16.0.7]

does any one know how to resolve?
