Overbridge issue

Hi all,

my good old 2011 Mac book pro is total scrapped, so I bought a new Mac book pro.
Now I have installed all my soft and hardware to the latest version.
The Mac book is running with os version 10.13.3 and my Rytm with the version 3.16.
It is not possible to get a connection via Overbridge.

Do you have any advice for me, what I can check to fix my Overbridge issue?
