I have hosted feature service and using AGOL with collector. It was working just fine. For some reason now I can only access my maps is I am connected via wifi on my company network (same network the GIS server is on). If I try to access over cellular, I get error cannot load layer (times out). switch wifi back on and it works fine. connect to different wifi network and it cannot load layer. (settings are configured to download and sync over wifi AND cellular...even though I am not trying to sync). Any ideas? It just started happening. iPad Air - ios 8.1 - newest version of collector.
I have one of the redlands sample maps configured for collector also. It works fine regardless of how I am connected. Its only my hosted feature service maps that are affected.
