Thanks Robert!
The portal URL was set up using https and I believe the organization is set up to require https. I set up the organization this past year and checked that box recognizing that was where things were going in general. Esri has taken away the option at this time.
We were able to deploy the app on a server with https configured. The app works properly in Chrome and Firefox, but not IE. In IE, it switches into IE 8 enterprise mode via the X-UA-compatible meta tag. I was able to switch it in the IE 11 developer tools to IE 11 mode and the app worked. I am wondering if we have group policy settings for our internal servers that change the mode to IE 8 for compatibility purposes. The Amazon hosted version of the app doesn't switch to IE 8 enterprise mode.
