Reported by John Roberts on 2016-01-22:

*Either the self-signed certificates or SSL itself prevent the ImageJ plugin from connecting.  
Adding a server and adjusting the url from http to https generates a "cannot connect to this server" message.
After turning off SSL in Orthanc, the ImageJ plugin default settings show the Orthanc server contents.*

Note that this works properly when a proper HTTPS certificate is available (e.g. if connecting to the demo server at http://orthanc.chu.ulg.ac.be/demo/).
