    This might not be the correct forum to address this problem. The plugin is working find, but your external resource is not allowing access due to invalid authentication. I would start with Postman and create the same query to the external service. Get it up and running in Postman and you'll figure it out.

    A tip for Postman is that once you have your query up and running you can use it to generate C# for instance. At least see what headers to set to help you create a proper request from the plugin.

    Hi

    The most likely cause of this error is that CRM is not able to reach the REST endpoint service.  Where does your REST endpoint live?

    You might have to update the Firewall / Proxy servers to allow the incoming request from CRM Online.

    You will have to liaise with your IT team to allow the CRM Online IP to access the REST endpoint.

    If you would like to know which IPs should be whitelisted, please visit the link below.
