Hi all
I’ve set up an instance of OpenEdX on Microsoft Azure
Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-155-generic x86_64)

I’m trying to get a tool from Cognii.com <http://cognii.com/> integrated as
via LTI and I’m having trouble. The outbound link - to go to the external
tool - works fine but it won’t pass the grade back.
During an LTI grade passing attempt,
*This is what is logged in my LMS:*

*This is what the LMS sends back to Cognii:*

Has anyone seen this? Any suggestions on what I might be doing wrong? I
believe that this tool has been found to work on other instances of OpenEdX.
Thanks for your time.
