Registry failure

This is now failing:
curl --silent --header "Authorization: Bearer

Where is the “field” result of: curl --silent “

It is failing for all of my container images, which is now suddenly breaking our product for all of its users.
I had been working for years. Was there an API change?

To clarify: The curl is now returning nothing (no error). It previously returned the json.

The problem resulted in a change to DockerHub’s response to a registry/v2/blobs request. Previously, when a HTTP Temporary Redirect (e.g., to occurred, that response was reported by curl. Now, a redirect is not reported by curl unless the verbose (-v) option is provided. And then, it comes back as STDERR instead of as STDOUT.
