I notice the Lets Encrypt SSL only generate for non www domain only when access with www.domainzz.com the cert is invalid

Sounds like you might want to create a wild card SSL cert. You will want to run your own SSL cert process as the internal one is really focused on bootstrapping basic SSL for those who do not understand what it is or how to do it.
