Creating a ManagedCertificate results in “Status: FailedNotVisible”
问题 Using Kubernetes 1.12.6-gke.7 or higher it is possible to create a ManagedCertificate which is then referenced from an Ingress Resource exposing a Service to the Internet. Running kubectl describe managedcertificate certificate-name first indicates the certificate is in a Provisioning state but eventually goes to FailedNotVisible. Despite using a Static IP and DNS that resolves fine to the http version of said service all ManagedCertificate's end up in a "Status: FailedNotVisible" state.
