Roon lost my Metrum Ambre -help


Help!!  Inserted a power conditioner in my system.  Everything got disconnected from power, then got powered up.  Everything works fine EXCEPT, I am not able to stream music thru my Metrum Ambre.  The LAN light is on, but the audio zone seems to be lost on the Roon screen. It doesn’t show up on my iMac or my iPhone as one of the audio zones available.
Can anyone help?

Can you delete and reinstall Roon?  Not a Roon user, so I don’t know if that is possible 
I got it working. Disconnected the Ambre from the “ether”, turned it off, reconnected the Ambre to the ether, then powered it up again.
