Question

What is the cause of the http: proxy error: x509: certificate signed by unknown authority when starting kubectl proxy with a specific IP of the node?

kubectl proxy --port=8001 --address=172.31.0.16 --accept-hosts='172.31.0.16'

I1222 09:00:03.471836   16775 logs.go:41] http: proxy error: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")
