Re: Unable to execute service GetRemoteMetadata

Ari,

 

First thing I would check is permissions.  Does the user who is assigned to that application key have permissions to execute GetRemoteMetadata on PiThing?

 

Next, validate that the EMS itself is working.  From your log, it appears to have connected successfully.  You have virtual directories - are you able to browse them using the RemoteThingWithFileTransfer services?

 

This issue may be with the server at ptcu-thingworx83-fundamentals.portal.ptc.io.  As a Thingworx Academic user, you don't have full administrative privileges like you would if you had your own system.  That system was designed so you could complete the labs in the Thingworx Fundamentals online course, which doesn't include connecting to an AlwaysOn(tm) agent in this manner.
