Workflow Manager Suspends Workflows - "Invalid JWT token"

Question

Hi,
I've installed Workflow Manager with the default settings described in this Technet article:
http://technet.microsoft.com/en-us/library/jj193514.aspx. Everything seems to install just fine but when I create a very simple workflow test on an "Announcements" list which simple
creates a Workflow History entry. However, the workflow immediately suspends with the following error which seems to be some kind of an authentication error. I am running the workflow logged on as a site collection administrator which is not 1. farm administrator
or 2. the service ID that I input into the Workflow Manager Configuration Wizard.I also DO have profiles installed, the user running the workflow DOES have a profile and I DO have the App Management service application installed. In addition, I rebooted the
SharePoint VM after the install
Given that Workflow Manager, Workflow Manager Client 1.0 and Service Bus 1.0 are all running on the same server as Central Administration (since I only have the one SharePoint VM) perhaps the reference to "SAMEORIGIN" in the error means something?
I've installed Workflow Manager with the same instructions on other farms in the past and not had this problem and wondering whether the June 2013 CU has introduced this error. . .
Please help!

Hi,
Base on the description, an unhandled exception occurred during the execution of the workflow instance.
I suggest you to use other account to test the workflow. Please make sure you are not using system account. Also please make sure User profile service is running and syncing with active directory. As I've found sometimes workflow tries to read user information
from user profile service and if the user details missing in User Profile service, the workflow might get failed. The original error is "Token Contains Invalid signature" which means either the user is system account or the user doesn't exists in user profile.
There is an article about the error message, you can refer to it:
