[Question] Device showing Down in Status after sometime

### Question

Initially it works fine but after sometime devices are showing down, however devices are up and running. Also at that time I am not able to add any devices, they takes loading time more than usual and it will not add anything.
Any Idea on this?

No file, test, or entry point is named. Start by reproducing the delayed device-down status and the stalled device-add behavior, then use the available issue details to identify what prevents monitoring and device creation from responding; done means explaining and resolving both symptoms.
