<_InactiveRpcError of RPC that terminated with:

ERROR:root:GRPC Exception:  DNS resolution failed for https://nnxx.com/: C-ares status is not ARES_SUCCESS qtype=AAAA name=https is_balancer=0: Domain name not found

My code 

BASE_URL = "https://nnxx.com"  # opens chirpstack v4 UI
channel = grpc.insecure_channel(BASE_URL)
device_stub = api.device_pb2_grpc.DeviceServiceStub(channel)

I believe this is not related to the Docker example but with your gRPC implementation.

BASE_URL = "https://nnxx.com"

In most cases, gRPC clients are not using the protocol prefix (https://) in your case.
