[FileSight] 'Easy Deploy' doesn't show new server

I've used Easy Deploy to install the Filesight service to a remote server, but the new remote server isn't showing in the central console.

The remote install appears to have worked as expected. I can see the service running on the destination server, and I have the 'Configure PA File Sight Ultra Satellite'.

Running the configuration utility on the remote server shows a configuration page. Clicking on 'test connection to service' returns a 'Connection test succeeded.'

However at the top of the utility is a scrolling status bar saying :

Satellite service is running. Unable to connect to Central Management server. - timed out while trying to connect

To test what is failing I have:
1. Confirmed that https://NATTHN50:8000/$INSTALL_PATH$/Setup.exe is available
2. Telnet NATTHN50 8000 opens a connection and returns an HTTP 400, as I would expect.

I just can't see a way of getting this server to show in the central console. Your thoughts please?

EDIT
Service on remote server was running as LOCAL SYSTEM, so I have updated that to use a domain administrator account (just during testing purposes). This required a restart of the service, but its still not shown up on the central console / I can't find how to get it to monitor any file systems.

EDIT 2 On the File Sight Ultra Console, under 'Satellite Services' left hand tab, I can expand and see the two systems I have attempted to push the satellite service too, both are showing as :

The Satellite Monitoring Service is not currently connected. Check:
•Verify the address that the Satellite is using to connect to the Central Monitoring Service
•Ensure that the Satellite can reach the Central Monitoring Service
•Check that the Satellite service is running
