Hi i'm still new to BC and i'm running into this error while executing the Send Method of the HttpClient ( Same error occurs when using the Get Method directly ). I have no idea why i'm getting the error since i can't see the line of code in said method that's causing it. Also the same URI + Authorization works perfectly fine in Postman or the REST Client extension.
the Authorization is stored in HttpClient.DefaultRequestHeaders() if you're wondering.
EDIT: It seems as though that the machine that the container is running doesn't have the permission to connect to our ESB. Will update shortly.
