I have installed the Philips Hue Light Starter Kit (Bridge + 2 White Lamps). Yesterday this worked well and I could control it via App or Alexa. Today the Hue Bridge disconnected from network and I'm not able to reconnect it. I restarted my Fritzbox-Router, I turned off/on the lamps manually and I restarted the Bridge. I changed the Ethernet-Cable and LAN-Port on the Router. No way to get a connection.
The Hue Bridge shows power-lamp on but ethernet and Internet lamps are off. Hue App tells me there is no connection as well. I also can't see the Bridge on my FritzBox. Someone has an Idea?
