I tried to retrieve the contents of the queue of one of my devices (LoRaserver version 2.6.1). As a result, the response text and response code are returned, as you can see in the picture.
In LoRaserver version 2.6.0, the node has received downlink and the queue have not returned any error. However, after updating the server to version 2.6.1, the node no longer receives downlink.
The firmware version of the node is still the same and I only have this problem with this node.
Does somebody has any idea?
