Well… that’s misleading.
There is no such thing as “denied” in LoRaWan - there is merely, “did not receive an accept”. - but that could either because the request was not accepted, or because there was a communication issue in either direction, including a confusion over frequency if a node too close to a gateway overloads it and falsely appears on channels other than the true one.
But when i look on the gateway it says the join IS accepted and shows som payload data…
Please be specific: Please show both the join request message, and the resulting join accept response.
