iOS app on iPad not finding/connecting with OSX app on iMac

Any ideas ? I tried logging out of both and restarting both. iOS app just keeps looking for OSX server and never finds it. Both running on same wifi.

 

Fixed this now. A second uninstall of the ipad app and a hard rebot of the iPad. followed by a re-install of the iOS app on the iPad and it is working now -well I see an iMac and a MacBook Pro, which are the servers I have set up

 

I had similar issues until I reinstalled the apps on the Mac/Windows machines. I suspect those on the beta were somehow connected to a non-production environment (thus the hosts were signed into a beta environment whilst the iPad was signed into production).
