I can log in to my portal from a PC, and i can log in to my AGOL account from the phone.
My Portal is set up for IWA.
I get the same thing after upgrading to iOS 8.0.2
For variety I also sometimes get:
The operation couldn't be completed. (NSURLErrorDomain error -1012.)
I found if I do a hard reset (on/off button and home button held down together) then I can login the FIRST time only. Does this 'work' for you?
We had to have Collector completely killed, not just running in the background, for the hard reset to work.
I received this error in the middle of working on ArcGIS Online on my desktop PC - asking for my username and resetting the password allowed me to log back in again.
