Netty connect() throwing io.netty.channel.AbstractChannel$AnnotatedSocketException: Invalid argument exception

Ask Question

This is the portion of the sample code I wrote

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
This is the Exception printed in the terminal
io.netty.channel.AbstractChannel$AnnotatedSocketException: Invalid
argument: www.google.com/172.217.194.105:48830
Is there a reason for this error? What's the fix?

                just a guess (as the exception is thrown from the JDK itself)... Can you ensure you bind to an ip4 address?  b.connect(remote, new InetSocketAddress("127.0.0.1",8536)).sync()

                @NormanMaurer b.connect(remote, new InetSocketAddress("127.0.0.1",8536)).sync()  this works without any issue
