This issue is known by Wyze and the possible cause is an AWS outage. They’re working on it! More information here:
I’m unsure on this because I don’t have the lock, but I believe that it is connected via Bluetooth. It may also connect to the gateway, but again not too sure on this!
@Brlepage from your link to the Service Status Known Issues - If the Gateway is offline, it will affect remote unlock/lock control. However, local control through Bluetooth would still be functional. Also, the keypad connects through bluetooth to the lock itself.
