Audirvana 3.0.7 stop working when I launch the iPad remote control.

Hello,
I’m using Audirvana 3.0.7 on a macbook Air with Sierra 10.12.5.
now when I run the A+ remote on my iPad,
the Audirvana 3.0.7 stop working.
I try to run the database clean utility no improvement.
I try to make a new remote association no improvement.
I try to remove the iPad A+ remote application and download again no improvement.
Regards.
