My project spontaneously lost the connection to the Mac host. I deleted everything from %localappdata%/Xamarin/MonoTouch and emptied the authorized_keys on the Mac host. I tried to login then under credentials. Xamarin can log in to the Mac host because the keys are regenerated on both machines and written to authorized_keys, yet Xamarin will not connect. No problems under PuTTY. Not a network issue. Can you help?
