We are not able to get our maps in portal to download offline using collector when the map contains a scanned tiff image that we georefference. The map in settings says it can go offline and in collector the option to download map offline is given. However when we attempt to add an offline area the progress circle starts up and then about 10 seconds later it disappears and and backs us out with no error messages and also no offline areas. The map works fine when you have connectivity.
We have made the exact same maps in the ESRI hosted Online environment and everything works offline. This leads me to believe it must have something to do with our Enterprise/Portal environment which currently is just a base deployment on a single machine. Or something with the collector app that interacts differently with portal then online?
Any help would be greatly appreciated
