Problem:

default CA created by kubeadm command during cluster initialization its not working properly.

open dashboard in my chrome browser because its complaining CA is not secure and not signed.

Please share any link or docs where explain how to deploy kubernetes cluster with self sign cert.

Hi,

There may a problem with firewalld. You need to disable your firewall permanently. There are some programs that the firewall will not allow.
