I am trying to consume REST services from a QlikSense server, running on a windows virtual machine in an AWS cloud slot. I succeeded in calling a REST service with Postman, but am running into problems when calling the same service from my Mendix app on my local machine (developemnt environment). The problems I encounter have the same symptoms when trying to reach a webservice when working behind an internet proxy server. I tried setting the https.proxyhost and port in my project settings but without success. Has anybody any experience in calling a REST service with above mentioned architecture? Can somebody give me pointers on where to look?
