i dont understand which node or system are cauese that problem and how can i stop it

2

It means that the Class-C is trying to schedule a downlink for a device which hasn’t sent its first uplink yet. In the next release, this will no longer be logged as error :slight_smile:

3

so its not fixing, or stopping,

is there any thing to reset these query or command to flush?

because whenever we stop and start server, it keeps runs and show error

4

ChirpStack requires that the device first sends an uplink, before it starts scheduling Class-C downlinks to the device. Currently this is noisy in the logs (which as I said will be fixed in the next release). However, you would still have to wait until the device sends its first uplink, before Class-C downlinks will be scheduled.
