I made a recording on my iPad Air with Capture Duo and can'r share it to my iMac (2015 iMac Retina 27 with OS Sierra). I get the message "Please launch Studio One on your Mac or PC and make sure it's on the same WiFi network as you iPad"

I've made sure that they are on the same network and that the remote device sharing is turned on and that the port 47809 is set in the dialog in the Airport Utility. Still no luck.

Any ideas? If I can't get the recording onto my Mac, Capture Duo isn't of any use.
