I am trying to setup a private repository where I want to push both linux and windows based images. The registry setup seems to be missing something or I have not configured it properly or have the wrong version.
The registry is setup on Ubuntu1604. I can push and pull images from the server itself using the local client. However when I try to push from another machine it does not work.
These are the log messages:

The only difference my #noob eyes see is that the registry server’s docker version is lower than the client server’s docker version.
Could really use another set of eyes!
