What does this error mean? I am getting it in response to a SOAP call to GetListItems. There is no description text.
I am authenticated and can successfully call this from SPServices(), but not through a custom call I am making from iOS.
This is not a SP error code but a client side (iOS) error code.

Also, try connecting using a Windows OS. Do you still have this issue? If yes, then the next step is to investigate the log records on the SP server.
