Adding layers from My Content

[PatrickRoyer]

I'm unable to add, or even find, any layers from "My Content", even though they are uploaded to "My Content".

All,
I noticed this issue as well - in the previous version of ArcGIS Explorer Online I was able to do this, but it seems something in the upgrade now causes this to fail. We tested the request with Fiddler and discovered the following:

It seems AGX Online uses a proxy in order to get to internal resources. For example, we have an internal server called TESTDEV that has a map service at http://testdev.esri.com/ArcGIS/rest/services/KIF/MapServer. 

When accessed through the normal Javascript web map it fetches tiles directly from the REST endpoint. 

When accessed through ArcGIS Explorer it attempts to call the following: http://www.arcgis.com/sharing/proxy?http://testdev.esri.com/ArcGIS/rest/services/KIF/MapServer?f=jso... but fails with the following error:

HTTP Status 500 - server encountered an internal error () that prevented it from fulfilling this request.

Does anyone know why this happens?
Thanks,
Pete

Pete,

If your service is not public, you need to make sure that your server has a clientaccesspolicy file.
