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?
