I have received my generic node, though I cannot claim the device. The proposed link Claim a Device | The Things Stack for LoRaWAN works only for the Industries stack, though I am on the community stack. I tried The Things Network Device Claiming Server{my app-id} which opens a dialogue and the camera, but when I scan the QR code on the back of the node, it reports an error 10, “no claim authentication code”. Any help appreciated
