The Light Panels unreachable error usually indicates 1 of 4 things:
- Your mobile device is on a different network from your Light Panels
- Your Light Panels have lost connection to your network
- The Light Panels can no longer be found on the local network
- The Light Panels are undergoing a firmware update
If you are setting up the Light Panels for the first time, there may be a required firmware update that happens shortly after setting up. The controller will indicate that the firmware update is downloading by the LEDs on the Nanoleaf Controller (beside the 2 buttons) flashing back and forth. Please wait 5-10 minutes and the update will complete.
For the remainder of the cases, please try the following steps:
- Ensure that the Light Panels are receiving power using the buttons to toggle power or change a Scene.
- Ensure that your mobile device or tablet is connected to the same network as your Light Panels
- Try toggling your Wifi on your phone or tablet off, waiting 10 seconds, and then turning it back on again. If this does not work, try closing the app and then re-opening
- Check that the Wifi indicator is off (the LED beside the 2 buttons). If it is flashing every 4 seconds, this indicates the device has lost connection to your Wifi network.
- Unplug the Nanoleaf Controller from power (the wall outlet) and plug it back in
- Try a soft or hard reset - making sure to delete the Light Panels pairing – from the app and then setup once again.
In some cases, router configuration settings can affect reachability. In particular, check for the following settings:
- UPnP (enabled)
- Multicast (enabled)
- IGMP Snooping (enabled)
- Client/AP Isolation (disabled)
One other option to test relies on the Wifi channel the router is using. Most routers will default to auto-select the optimal channel, which usually works well. However, with some models, this can cause issues in how the router communicates with your Light Panels. Selecting a fixed Wifi channel can help to mitigate this unreachability. The recommended channels are 1, 6 or 11.
