Help: Cannot start Bootstrap

[GameduJS]

Hello,
I have been working on a small project where I have a server and a client.
My problem is that I can't start the client, it gives me the following error:

Using Netty 4.1.79.Final, JDK 17

Exception in thread "main" java.lang.UnsupportedOperationException at io.netty.channel.socket.nio.NioServerSocketChannel.doConnect(NioServerSocketChannel.java:178) at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe.connect(AbstractNioChannel.java:248) at io.netty.channel.DefaultChannelPipeline$HeadContext.connect(DefaultChannelPipeline.java:1342) at io.netty.channel.AbstractChannelHandlerContext.invokeConnect(AbstractChannelHandlerContext.java:548) at io.netty.channel.AbstractChannelHandlerContext.connect(AbstractChannelHandlerContext.java:533) at io.netty.channel.AbstractChannelHandlerContext.connect(AbstractChannelHandlerContext.java:517) at io.netty.channel.DefaultChannelPipeline.connect(DefaultChannelPipeline.java:978) at io.netty.channel.AbstractChannel.connect(AbstractChannel.java:265) at io.netty.bootstrap.Bootstrap$3.run(Bootstrap.java:250) at io.netty.util.concurrent.AbstractEventExecutor.runTask(AbstractEventExecutor.java:174) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:167) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:470) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:503) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:997) at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.base/java.lang.Thread.run(Thread.java:833)

Here's my code:

`
boolean epoll = Epoll.isAvailable();

    EventLoopGroup eventLoopGroup = epoll ? new EpollEventLoopGroup() : new NioEventLoopGroup();

    try {
        Bootstrap bootstrap = new Bootstrap();
        bootstrap.group(eventLoopGroup);
        bootstrap.channel(epoll ? EpollServerSocketChannel.class : NioServerSocketChannel.class);
        bootstrap.handler(new ChannelInitializer<>() {

                    @Override
                    protected void initChannel(Channel channel) {


                    }

                });
        ChannelFuture channelFuture = null;
        try {
            channelFuture = bootstrap.connect("127.0.0.1", 1234).sync();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        channelFuture.channel().closeFuture().syncUninterruptibly();
    } finally {
        eventLoopGroup.shutdownGracefully();
    }

You're using server socket channels but trying to build a client. Use the non-server channel variants.

Oh yeah, totally missed that, thanks anyway
