An example of a push

looking in the logs i can see it also say a post is unallowed.
I noticed there is an option to allow push in /etc/foreman/plugins/katello.yaml
I set that as follows

    :crane_url: https://katello.redacted.com:5000
    :crane_ca_cert_file: /etc/pki/katello/certs/katello-server-ca.crt
    :allow_push: true

However I still end up with the same outcome.
A docker login works just fine.
Is there something I am missing? or not understanding?
I have created a product as follows
Products > Kubernetes_Docker_Registry > Repositories > kubernetes-prod

Which indicates its Published At : katello.redacted.com:5000/redacted-kubernetes_docker_registry-kubernetes-prod
