Issue in Reactive gRPC streaming: Sending GOAWAY failed:'Connection reset by peer'. Forcing shutdown of the connection. Broken pipe

Hi guys,

I am implementing a gRPC client server in spring boot java with stream of outputs.
With BloomRPC server is working fine. But when I am connecting server with client then on CLI of client it shows "io.grpc.StatusRuntimeException: UNAVAILABLE: io exception".

On CLI of server it shows "Debugger failed to attach: handshake failed - received >PRI * HTTP/2.0< - expected >JDWP-Handshake<"

In the logs of of client application I can see the below logs,

grpc-nio-worker-ELG-1-4] [] DEBUG i.g.n.s.i.g.netty.NettyClientHandler - [id: 0x2551465d, L:/127.0.0.1:61456 - R:localhost/127.0.0.1:6565] OUTBOUND SETTINGS: ack=false settings={ENABLE_PUSH=0, MAX_CONCURRENT_STREAMS=0, INITIAL_WINDOW_SIZE=1048576, MAX_HEADER_LIST_SIZE=8192}

java.io.IOException: Broken pipe

Any help would be highly appreciated.

P.S. I am using a reactorGrpc stub like
@GrpcClient("hello-client")
ReactorHelloGrpc.ReactorHelloStub stub;

And then in method,

Flux<Output> flux=stub.Hellomethod(Input of Mono)

It seems like you are pointing the client at the wrong port. JDWP is the Java remote debugging protocol.
