Copied here from IRC as I didn’t get an answer 
Hi I was wondering if someone could point me in the right direction, I’ve setup a couple of docker registries now for clients and not once have I had this kind of issue, I get the issue on docker for mac beta AND docker for mac using virtualbox (kitematic) with docker-machine. When I push an image to the new registry, I can see entries going into S3, and the requests in the registry logs but the client gets into a weird state where it says retrying etc - here are some logs https://gist.github.com/danjenkins/dbfd0ca7dbb0e83d96cb66fff8ed0bc0 but I’m not really sure where to go from here
Oh, I say S3 above but I also changed the registry to just use memory as the storage to make sure it wasnt something with S3… as you can see in the logs, using inmemory as storage and it still fails
It looks like the server thinks everything went OK but the client thinks differently…
I dont understand the host lookup failing because its there… I did a dig etc…
