Affects Version/s: 3.0.0
Fix Version/s: None
Running Nexus in k8s via then Helm chart.
Problem occurs with the docker Repo, I believe nexus-proxy has nothing to do with it.
When trying to push images with buildah, buildah first pings my.nexus-docker.server/v2. This URL always results in a 401, when "Allow anonymous docker pull" is enabled for the Repo.
This is also reproducable if you just login as admin and call the URL manually.
my.nexus-docker.server/v2/a or any other than the "root" URL is working.
As soon as you disable "Allow anonymous docker pull" you no longer get unconditional 401 responses.
