An existing connection was forcibly closed by the remote host

[kesha...@javra.com]

I using the following environment. 

Windows 7 64 bit.

Java : jdk1.8.0_131

protobuf-gradle-plugin:0.8.1

protoc:3.3.0
protoc-gen-grpc-java:1.4.0


But while running the project I get response for first call only and on server side I obtain following error after that.

io.grpc.netty.NettyServerTransport notifyTerminated
SEVERE: Transport failed

Can any one suggest me the solution why this is happening?

Could you try channel.shutdownNow() instead of shutdown()?  

I think that logged message is somewhat of a hypochondriac.
