This is most likely the result of your Wi-Fi Doorbell Chime losing connection to the Internet.

For Router

1. Make sure your router can access the Internet successfully.
2. Make sure if you have enabled DHCP on your router.
3. Try to turn off the firewall setting on the router.

For Wi-Fi Doorbell Chime

1. Try to restart the Wi-Fi Doorbell Chime by unplugging it from the socket and plugging it in again. It may recover after 3 minutes.
