Messages not sent to the cloud

All the 4 modules are up and running and I can see the following with docker logs in the Forwarder

So there are lots of messages, some are really simple like this: JSON up: {"stat":{"time":"2020-10-23 06:10:23 GMT","rxnb":2,"rxok":0,"rxfw":0,"ackr":100.0,"dwnb":0,"txnb":0}}

Which I am going to suppose that this is a Status message from the device to cloud.

and then I get this: [{"tmst":432653204,"chan":4,"rfch":0,"freq":867.300000,"stat":1,"modu":"LORA","datr":"SF12BW125","codr":"4/5","lsnr":-1.2,"rssi":-108,"size":28,"data":"QADhrL4AAQABWSbyd2uv6M/AzxDz5sEQ/lIzFg=="}]}

which I am going to suppose is the payload of my lorawan sensor message which I have to decode.

However, no messages are received in IoTHub. I tried to monitor via the endpoint using VScode and Visual Studio but I get this error which I dont know how to troubleshoot.

[IoTHubMonitor] Start monitoring message arrived in built-in endpoint for device [58a0cb00001087ed] ...

[IoTHubMonitor] Message monitoring stopped. Please try to start monitoring again or use a different consumer group to monitor.

I did a test using a .net core app to send messages to the cloud : https://docs.microsoft.com/en-us/azure/iot-hub/quickstart-send-telemetry-dotnet and this works perfectly fine.

Can you give me advice in how to troubleshoot?
