LorixOne to GCP pubsub messages not reaching

I am trying to integrate GCP with loraserver using LorixOne Gateway, I am following the guide at https://www.loraserver.io/guides/google-cloud-platform/
However my messages not reaching to loraserver through pubsub.

My setup is as below:
lora end device—>LorixOne Gateway with Lora base OS —> GCP IoT core -> GCP Pubsub —> VM running loraserver

I can see that all messages are reaching to IoT core but nothing can be seen on the pubsub or lora-app-server.

Can you support what could be wrong with pubsub?


Its resolved, It was issue with end loraWan device with AU band !!
