grpc.channel_ready_future(channel).start()
except grpc.FutureTimeoutError:
sys.exit('Error connecting to server')

It seems that the client is failing to connect to the server:

"failed to connect to all addresses",

Are you sure that the server is listening on that port? Try running netstat on the server to verify. Are there firewall rules getting in the way? Try using nmap from the client to verify.

I had the wrong server IP. Thanks Richard
