Problem seems to be fixed.
I was using a USB-hub with my Macbook and now I tried using and USB-C/USB-C cable instead and the H90 connects to H90 control. The strange thing is that the USB-hub worked just fine with the H90 for a few weeks but for some reason it suddenly stoped working and the computer had no connection with the H90.
A big thanks to Eventide support for helping me.
