netty-incubator-codec-http3:server create stream to client push data fail

Question

In my Netty-incubator-codec-http3 application, the server creates a new stream to the client, calls writeAndFlush(), but the client doesn't receive the data.

Client and server successfully connect and create an initial bidirectional stream. Server-initiated streams, created over the established QuicChannel, are not delivering data to the client, despite the connection remaining active.

    //server

        ...
        try {
            Bootstrap bs = new Bootstrap();
            Channel channel = ....sync();
//i want to send data to client test
            ScheduledExecutorService timerExecutor = new ScheduledThreadPoolExecutor(1);

            timerExecutor.scheduleAtFixedRate(
                    () -> {
                        try {
                            hand();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    },
                    5, 5, TimeUnit.SECONDS);


        } finally {
            group.shutdownGracefully();
        }
    }

   private static void hand() {
//QUIC_CHANNEL_LIST :client connect to server success,server save it
        for (QuicChannel quicChannel : QuicServerExample.QUIC_CHANNEL_LIST) {
//it is my protobuf
            TdataProtoBuf.Tdata request = TdataProtoBuf.Tdata.newBuilder()
                    .setQueryKeyBlob("server-asd123123f")
                    .build();
            NettyMessage nettyMessage = new NettyMessage("lty.TdataProtoBuf$Tdata", request, 0);
            try {

                // explicitly create a new stream and send data
                QuicStreamChannel streamChannel = quicChannel.createStream(QuicStreamType.BIDIRECTIONAL,
                        new ChannelInitializer<QuicStreamChannel>() {
                            @Override
                            protected void initChannel(QuicStreamChannel ch) {
                               // my  Decoder and Encoder
                                ch.pipeline()
                                        .addLast(new ProtocolV1Decoder())
                                        .addLast(new ProtocolV1Encoder());
                            }
                        }).sync().getNow();


// after executed streamChannel.writeAndFlush .
//no log output include send success or    send error... 
         streamChannel.writeAndFlush(nettyMessage).addListener(future -> {
                    if (future.isSuccess()) {
                        System.out.println("send success");
                    } else {
                        System.err.println("send error: " + future.cause());
                    }
                });

            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }
