这是我编写的示例代码的一部分

b = new Bootstrap();
        var remote = new InetSocketAddress("www.google.com", 8080);
        b.group(group)
                .channel(NioDatagramChannel.class)
                .handler(new ChannelInitializer<Channel>() {
                    @Override
                    protected void initChannel(Channel channel) throws Exception {
                        channel.pipeline().addLast(new MyHandler());
                    }
                });
        var cf = b.connect(remote, new InetSocketAddress(8536)).sync(); // this line throws Exception

这是终端中打印的例外情况
io.netty.channel.abstractchannel$annotatedsocketexception:无效参数：www.google.com/172.217.194.105:48830
这个错误有什么原因吗？有什么办法？
