My Hue Bridge was working for about 2 years. One day I found that I couldn't connect it. Looking at the device I can see that the third light (internet) is off, and it doesn't show up in the Hub 3's list of connected devices. I've tried various things:
- Power cycling the Hue and the Hub 3
- Factory reseting both devices
- Running the Hub 3 diagnostic tool
- Switching ethernet ports
- Assigning a static IP to the Hue Bridge
Interestingly, if I run the Hub 3 diagnostic tool, the following happens:
- "Philips-hue" reappears in the list of connected devices.
- The 3rd light (internet) is now on and solid
- As soon as I use the Hue app to try and connect to it again, the device is booted off the Hub3's devices list.
- At which point the 3rd light turns from solid to blinking
