Philips Hue LED disconnects frequently

Schermata 2021-11-05 alle 10.15.47

This is my current situation, with HA OS v6.6 and HA Core v2021.11.0, with the grey lines signaling the disconnected state of the Philips Hue LEDs.

Is there something I can try to at least mitigate the problem?

Any hint? Someone with the same experience?
