java.io.IOException: Указанное сетевое имя более недоступно

Создал простой асинхронный клиент-сервер, при подключении клиент посылает на сервер сообщение, при попытке принять сообщение на стороне сервера выскакивает исключение :

java.io.IOException: Указанное сетевое имя более недоступно.
at sun.nio.ch.Iocp.translateErrorToIOException(Unknown Source)
at sun.nio.ch.Iocp.access$700(Unknown Source)
at sun.nio.ch.Iocp$EventHandlerTask.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

вот клиент:

package fileSocket;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.AsynchronousSocketChannel;
import java.nio.channels.CompletionHandler;
public class Main {

public static void main(String [] args) throws InterruptedException, 
IOException {

     AsynchronousSocketChannel sockChannel =  
AsynchronousSocketChannel.open();
        //try to connect to the server side
        sockChannel.connect( new InetSocketAddress("192.168.0.102", 4555), 
sockChannel, new CompletionHandler<Void, AsynchronousSocketChannel >() {
            @Override
            public void completed(Void result, AsynchronousSocketChannel 
channel ) {
                //start to read message
                System.out.println("connected");
                //write an message to server side startWrite( channel, 
 message, messageWritten );
                ByteBuffer message = ByteBuffer.wrap("ping".getBytes());
                    channel.write(message);

               System.out.println("sadasdasd");

            }
            @Override
            public void failed(Throwable exc, AsynchronousSocketChannel 
  channel) {
                System.out.println( "fail to connect to server");
            }
        });


    }
    }

вот сервер:

 package ru.NewAgregatorServer.NewAgregatorServer;
 import java.io.IOException;
 import java.net.InetSocketAddress;
 import java.nio.ByteBuffer;
 import java.nio.channels.AsynchronousChannelGroup;
 import java.nio.channels.AsynchronousServerSocketChannel;
 import java.nio.channels.AsynchronousSocketChannel;
 import java.nio.channels.CompletionHandler;
 import java.sql.SQLException; 
 import java.util.concurrent.ExecutionException;
 import java.util.concurrent.Executors;
 import java.util.concurrent.TimeUnit;
 public class AppRPC {
 public static void main(String [] args) throws IOException, 
 InterruptedException, SQLException, ExecutionException {
AsynchronousChannelGroup group = 
AsynchronousChannelGroup.withThreadPool(Executors
        .newSingleThreadExecutor());
AsynchronousServerSocketChannel server
  = AsynchronousServerSocketChannel.open(group);
server.bind(new InetSocketAddress("192.168.0.102", 4555));
server.accept("Client connection", 
        new CompletionHandler<AsynchronousSocketChannel, Object>() {
    public void completed(AsynchronousSocketChannel ch, Object att) {
        System.out.println("Accepted a connection");
        ByteBuffer buf = ByteBuffer.allocate( 1024 );
            //ch.read(buf).get();
            ch.read(buf, buf,  new  CompletionHandler<Integer, ByteBuffer>() 
    {
                @Override
                public void completed(Integer result, ByteBuffer buf ) {
                    System.out.println( "received " + result + " bytes");
                    buf.flip();
                }
                @Override
                public void failed(Throwable ex, ByteBuffer buf) {
                    ex.printStackTrace();                   
                }
            });
            byte [] b = new byte[1024];
            buf.get(b);
            System.out.println(new String(b));
        }
       public void failed(Throwable exc, Object att) {
        System.out.println("Failed to accept connection");
       }
     });

     group.awaitTermination(Long.MAX_VALUE, TimeUnit.SECONDS);

      }

     }
