rbd-target-gw.service: Failed with result 'exit-code'.

Trying to get this initial setup completed. I did the ceph-ansible setup and can look at the dashboard and see things. Now trying to get iscsi working, but can't get gwcli get the following error:

sudo gwcli
REST API failure, code : 500
Unable to access the configuration object
Unable to contact the local API endpoint (http://localhost:5000/api)
