Nest protect wont connect (PO23 error)

[Kubla]

Have changed my WiFi provider and for some reason I am unable to get my 2 nest protect devices to connect to my new WiFi network, no matter what I try. Getting PO23 error code. Anyone got any suggestions?

Hi Kubla, 

Yikes! I'm sorry to hear that your thermostat won't connect to your new internet. Kindly follow these: 

1. Quit and restart the Nest or Google Home app.
2. Make sure Bluetooth is on. Turn Bluetooth off, then back on to refresh the connection.
3. Disconnect any Bluetooth devices that are connected to the phone to rule out any interference.
4. Put the mobile device on airplane mode, then turn on Bluetooth and Wi-Fi.
5. Restart the phone or tablet.
6. Restart the joining and assisting devices.
7. Move the joining device closer to the router, or the router closer to the assisting device.
8. Try a different mobile device.
9. Create a hotspot and try to pair again. Make sure that the device connects to the hotspot this time and not the home Wi-Fi.
10. Create another structure in the Nest or Google Home app and try to add the device to the newly created structure.
11. Try to add the device to another account. 
12. Reset the joining device to default.

Let us know how it goes.

Best,

Zoe
