grpc-go client disconnect in 60 seconds

[aagrawal]

Thanks for reply, 
So i can see that when i start grpc-go client insecure connection,  http
request is received by grpc server and response also sent from grpcserver in
every 10 seconds.
But still after 60 seconds timeout happens.

So is it correct to say that because of some issue grpc-go client request
body is not proper or something is missing in it.
Please advise.
