It’s look that you have wrong fre config on gateway.
Do you install lora-gateway-bridge on the gateway?

I use packet forwarder on Gateway.
I still receiving messages from devices over MQTT, but I have problem on azure service bus, but it worked before, now it doesnt work in service bus.
Did you found solution for you?
