I've got a data service we are using in one of our Javascipt API applications, both of which are served off our in house ArcGIS Server and web server. I've added the data service to a Web Map and published the web map to the public (http://arcg.is/OKa4O ). However, when I try to make a Story Map based upon that Web Map, the service refuses to show up. It tells me the service is inaccessible. Since it works fine in our current application and it seems to work fine in the Web Map, I'm not sure what to do with the service to make it accessible by the Story Map. Any suggestions?
