I recently developed a custom web application using Web AppBuilder SDK. I downloaded and unzipped the web app files and put them on my web server (IIS). However, when I go to access the application I only get the loading screen and eventually the connection times out and says the site can't be reached. It seems to be an issue with setting up a proxy, but I wanted to make sure that there wasn't something I was missing. Has anyone else had a similar issue?
