Audirvana for Synology: Pairing Initiate Failed!

I installed Audirvana Origin beta (2.5.12.4) on Synology NAS. It is running but I cannot connect the remote. I get the message: “Pairing Iniate Failed!” when I try to connect to the NAS. Any hint what might be?

Do you have avahi/avahi-daemon installed and running? When you ask for the status of the Audirvana service, if there is a message, what does it say? (I’m not familiar with Synology in particular, so I don’t know how to find the status message if there is one.)

I had the idea that the daemon was included in Synology. I will try to find out.
Audirvana is showing as running and the NAS appears in the remote has available computer to connect.
