How do I configure PyCharm to work with a remote docker image?

My setup is as follows:

Local Machine- OS X, running PyCharm Professional 2018.2.4.

Remote machine- VPS running Fedora 26, docker 1.13.1, with remote API exposed on port 2376.

I have a copy of my codebase on both machines.  On the remote machine, it runs in a python docker container (it is a django project).  Now I am trying to configure the docker image on the remote VPS as a remote interpreter.  I have done the following:

Preferences --> Project Interpreter --> Add Python Interpreter --> Docker

On this screen, I created a new Docker, and set it to connect via TCP socket.  For the Engine API URL, I used "https://mydomain.com:2376" and supplied my cert/key directory.  Upon doing this, I see all of my remote docker images under the Image Name dropdown in the Add Python Interpreter dialog, so I know the connection/cert/key is set up properly.  However, when I click "OK" the "Get remote interpreter version" dialog that pops up gives me an error that "repository docker.io/pycharm_helpers not found: does not exist or no pull access"  Some googling has yielded suggestions to uninstall the pycharm_helpers image from docker, however docker doesn't have any pycharm_helpers image to uninstall.  I am not exactly sure how to proceed from this point.  Thoughts?
