Error when attempting to enqueue packets for download

I’ve been successful in enqueuing packets for download from the Lora Server Applications->[application name]->Devices->[device name] page, but periodically I get a popup with the message “enqueue downlink payload error: create device-queue item error: rpc error: code = InvalidArgument desc = device security-context out of sync (code: 13)” when I click ENQUEUE PAYLOAD.

For what it’s worth, I do have the frame counter validation disabled.

I have no idea what this means, why it chooses to appear, and exactly what action I do that clears it.

Any ideas?

It looks like the device performed a new OTAA and the Network Server did not notify the Application Server of the new security context. This context should be in sync after the first received uplink :slight_smile:
