Unable to receive sensor data after OTAA

While trying to connect a Netvox sensor with a Multitech gateway configured as packet forwarder to the loraserver, the system receives a join packet and another uplink packet but no sensor data is received.
As shown below:

There seems to be nothing wrong with the hardware, what more could we do to identify the source of this problem and solve it?

Thank you.

Above the Join I do see an Uplink :slight_smile: See also https://forum.loraserver.io/t/otaa-failed-debugging-device-activation-otaa-issues/474.
