I tried the plugin, but I get a black screen and:

> Unable to query for studies at this time. Check your data source configuration or network connection

I’ve been trying to get _something_ to work as shown [here](https://discourse.orthanc-server.org/t/role-permissions-issue/4559/10), but I’m still having trouble. I still can’t view images, whether it’s the plugin, or the actual ohif container.
