I have multiple apps configured with the same api manager authentication settings. Most of them run perfectly fine locally (as long as I include the correct authentication in the test api call). But ONE application I have, doesn't seem to be working, no matter what. I tried this, and it did work perfectly to get it to work, but I also like to keep the authentication intact, so that I can ensure that it is also configured correctly. Any idea what could cause this issue in a single app?
