any ideas why NBIoT stopped?

The upload vanished and I have no idea what happened. The battery voltage is still elevated, Even in case of theft there should be readings. The device planted remoetely might have died.

many thanks

Can you provide some more details please? What is NBiot? Is it your hardware? What kind of device is it? Do you know how it it communicating with ThingSpeak?

Narrow Band IoT Dragino - I could check whether the SIM card ran out of credit. Here the device management kicks in.
