Mosquito_sub can't receive message from nodes (MQTT)

Just like above,my app-server can log the message from my device,and mosquito_sub can receive message from gateway.But the mosquito_sub can’t get the message from device. What happened? Can anyone give me some advice? Thanks a lot!

Do you have any mosquitto authentication/authorization methods implemented?

lf you look at the architecture of lora,the device (packet_forwarder)send data by udp to gataway and then gataway send it to the mosquitto.

You need to make sure that your devices are properly activated. Else LoRa Server will reject these frames and will show MIC errors in the log output (this has already been covered by some other forum topics).
