HI Team,

I am using Multitech MTCDT-247A Gateway using Packet Forwarding option and I have installed lora-gateway-bridge in Multitech gateway. Updated MY cloud server IP in lora-gateway-bridge config file in Multitech gateway.

Google Cloud i have launched server Ubuntu 18.04 LTS & 16.04 Version. I have installed Loraserver & Lora-app-server.

am using Lora-app-server 3.3.1 & Loraserver 3.2.1 & lora-gateway-bridge 3.3.1 version in cloud server.

I have Created Network Servers,Gateway,Service,Device,Gateway,Application profile successfully.

I have added My Multitech gateway in gateway profile with out any issue.

I got error in logs creating Device/activating/reactivating device. Please find the below error.

unary call with code NotFound" error=“rpc error: code = NotFound desc = object does not exist” grpc.code=NotFound grpc.method=GetActivation grpc.service=api.DeviceService grpc.start_time=“2019-10-04T06:43:55Z” grpc.time_ms=4.474 peer.address=“127.0.0.1:58600” span.kind=server system=grpc
