LTI Caliper Profile service using the DVM

Does anyone know if the developer virtual machine instance of Learn 9 Q4 2017 has to be accessible from the outside world in order to make requests to the LTI Caliper Profile service?  Mine is not, and currently I get a 500 response with the message "An error occurred during a GET request to /telemetry/api/v1/caliper/providers/...".  If I do not sign the request or if I use an incorrect key or secret then I get a 401 response as expected, so it would appear that my request has passed the authorization checks.  The error generated is a "blackboard.plugin.cloud.ext.connection.CloudClientException" from "CloudRestClientImpl.java:248" and appears to have been caused by a "org.springframework.web.client.HttpClientErrorException: 404 Not Found" error.  The reference to "Cloud" makes me wonder if there may be an external connection involved here.

 

I have been unable to locate any documentation for the Learn 9 Caliper implementation at "help.blackboard.com"; if anyone knows where this is located, or what might be causing this error I would be very grateful to hear.

 

Many thanks and happy 2018.
