Requested access to the resource is denied during docker push

We have a working version for proget basic edition serving as a docker repo among other things in one office location. I am trying to demonstrate the value of having it in other locations so we can move to the enterprise edition. I installed the latest free edition on VM in a second location and set it up to match what we have in the first.

This setup includes using IIS on install; https binding with a cert for the proget site.
I also ensured that the NetworkService has full control access to the feed storage location)

When I try to push an image up to the repository I see this:
The push refers to repository [docker.io/<server name>/<feed name>/library/redis]

denied: requested access to the resource is denied

The same failure happens using anonymous or for a user I have created on the proget site, given push and view access to; and have done a docker login on the client before trying the push.

Any suggestions on what to try next?

Hello Eric,

I think Docker requires at least one . in the hostname, and it's trying to access the default Docker hub.

Another way that might work would be to add the port number to the hostname:

<server name>:443/<feed name>/library/redis

(the library part is optional to match the Docker hub, so <server name>:443/<feed name>/redis should also work)
