Thank you for the detailed report, including the screenshots; this is very helpful. A few comments:
- When you're saying that the calls are working fine in the local and staging environments, but not in the production environment, is this always when doing the calls from the "HTTP Service Editor" dialog in Form Builder?
- Are the calls always done over HTTPS, or is it HTTP in some cases and HTTPS in others?
- The call you're doing from the browser itself is a GET, but in the dialogs you've put POST as the method. Could you try changing it to GET, if GET works for you?
