How to Fix the Third Light Issue on Your Philips Hue Bridge?

If you're having trouble getting the third light to operate on your Philips Hue Bridge, there are a few things we can check to troubleshoot the issue. First, ensure that your Hue Bridge is connected directly to your router. If it's currently going through a switch or multiple switches, try bypassing those and connect it straight to the router that’s plugged into your internet line. All the lights on the bridge should be solid; if any are flashing, that indicates a problem. Connectivity issues often stem from the network configuration. If you have a modem/router combo connected to another router, consider moving the bridge to the modem/router combo instead. This can sometimes resolve connectivity problems. The bridge requires ports 80 and 3000 to be open, and your router should support Nupnp (Universal Plug and Play). If you can, share the model number of your router, as that might help with further troubleshooting. If the third or Internet light on your Hue Bridge is still flashing, try unplugging both the bridge and the router for about 30 seconds before reconnecting them. If the problem persists, try connecting the bridge to a different Ethernet port on your router and give it about five minutes to see if it comes back online. These steps should help you get everything working smoothly again.
