gPRC java：‘流的窗口大小溢出: 0’

Question

我的gPRC客户端应用程序收到一个'Window size overflow for stream: 0‘错误。我不能控制服务器。我尝试过使用.newStub()和.newBlockingStub()。我的Python客户端应用程序可以成功地与服务器一起工作，所以可能是Netty配置问题？

Gradle：

compile 'io.grpc:grpc-all:1.32.1'

通道/存根设置(此处无错误)：

channel = NettyChannelBuilder.forAddress(hostname, port)
.usePlaintext()
.maxInboundMessageSize(32000000)
.build();
blockingStub = AuthenticationServiceGrpc.newBlockingStub(channel);

调用存根方法时出错：

如果您怀疑Netty配置有问题，那么您一定是尝试过Netty配置，对吧？

您是否使用与服务器相同的gRPC版本？

您是否遵循了服务器控制者的配置指令？

P.S. Scala编译成Java字节码并使用Java库。
