Description of Issue

Roon just stopped working @ 4 days ago. I tried deleting the app from both the QNAP and my phone and tablets.
I get to the sign in screen and the Roon icon just shows for a few minutes then right back to the sign in screen.
In my QNAP NAS it shows as the ROON is running and it has the current version and is pointed at the correct data volume.

Have you rebooted your Qnap?

Hi @Claus_Blem

Is there any change after a reboot of your QNAP?

Were there any changes to your setup at all around the time this started occurring?
