Hi Noris, the Innuos is directly connected to the router via LAN, with no gear inbetween. I just checked, and the firmware is up to date.
Just a small correction to the above problem: When I enter my login data, Roon logs in if I just wait long enough. So my problem is pretty much exactly the same as described in this thread: Roon won't remember my login
I can see that you are already looking for a solution, so I’ll just wait and check regularly.
