grpc-cli return Received an error when querying services endpoint.

grpc version 1.3.0

jdk 1.8

add ProtoReflectionService after my service

private NettyServerBuilder initConfigServer() {
        Integer workers = Optional.fromNullable(providerSettingConfig.getIothreads()).or(0);
        NettyServerBuilder builder = NettyServerBuilder
                .forPort(registryConfig.getServicePort())
                .bossEventLoopGroup(create(Constants.NETTY_BOSS_EVEN_LOOP_GROUP, 1))
                .workerEventLoopGroup(create(Constants.NETTY_WORKER_EVEN_LOOP_GROUP, workers));
        logger.debug("server:netty boss:{} worker:{}", 1, workers);

        for (ServerServiceDefinition ssd : ssds) {
            builder.addService(ssd);
        }

        builder.addService(ProtoReflectionService.newInstance());

        return builder;
    }

then run

./grpc_cli ls localhost:50053

return

Received an error when querying services endpoint.

io.grpc.examples.helloworld.HelloWorldServer is the same problem too

I am also encountering a similar issue, with a trivial C++ server implementation. I can get a client to talk to the server, but I would like for grpc_cli to work as well.

One way to get a better error message is to set the GRPC_VERBOSITY environment variable:

$ export GRPC_VERBOSITY=DEBUG
$ grpc_cli ls 127.0.0.1:8082

@SeriousMa Are your failure details similar?

@minorhacks have the same issue as you, did you found any approach for this?
