Android Debug Bridge - Firesticks keep dropping off the network

Hi there.

Until recently, I used the Debug bridge without any issues at all.

I use HA to monitor when the status of the Firesticks turns to “off” and I use this to then turn off the TV, via a Zigbee smartswitch. I use Nodered for the automation and I have this set up for two TVs.

Over the past couple of weeks, I have noticed that both of the TVs were staying on and, when I checked HA, the status of both Firesticks was “unavailable”.

I unplugged the Firesticks for a few minutes and status returns to normal but then it happens again after a few hours.

Any advice to get everything working again?

I have no idea what has suddenly changed.
