java - Error writing to server

I am uploading a file from one server to another server using a Java Program 'POST' method. But I am getting below exception.

java.io.IOException: Error writing to server
    at sun.net.www.protocol.http.HttpURLConnection.writeRequests(HttpURLConnection.java:582)
    at sun.net.www.protocol.http.HttpURLConnection.writeRequests(HttpURLConnection.java:594)
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1216)
    at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:379)
    at com.test.rest.HttpURLConnectionExample.TransferFile(HttpURLConnectionExample.java:107)
    at com.test.rest.HttpURLConnectionExample.main(HttpURLConnectionExample.java:44)

I have other method who will authenticate with server. Which will be be called from below code. When I am getting response from server, I am getting above exception. To Transfer a file to server I have written below method. My sample code is below:

public static void TransferFile(){
        String urlStr = "http://192.168.0.8:8600/audiofile?path=1/622080256/virtualhaircut.mp3";
        File tempFile = new File("/home/MyPath/Workspace/Sample/virtualhaircut.mp3");
        BufferedWriter br=null;
        HttpURLConnection conn = null;
        URL url;
        try {
            url = new URL(urlStr);
            AuthenticationUser();
            conn = (HttpURLConnection) url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestMethod("POST");

            conn.setRequestProperty("Content-Type", new MimetypesFileTypeMap().getContentType(tempFile.getName()));
        } catch (MalformedURLException e1) {
            System.out.println("Malformed");
            e1.printStackTrace();
        } catch (ProtocolException e) {
            System.out.println("Protocol");
            e.printStackTrace();
        } catch (IOException e) {
            System.out.println("IO");
            e.printStackTrace();
        }

        System.out.println("line 69");


        FileInputStream fis;
        OutputStream fos;


        try {
            System.out.println("line 75");

                System.out.println("line 77");
                fis = new FileInputStream(tempFile);
                fos = conn.getOutputStream();
                byte[] buf = new byte[1024 * 2];
                int len = 0;
                System.out.println("line 80");
                while ((len = fis.read(buf)) > 0) {
                    fos.write(buf, 0, len);
                    System.out.println("line 85");
                }
                System.out.println("line 87");
                buf = null;
                fos.flush();
                fos.close();
                fis.close();

        }catch (FileNotFoundException e) {
            System.out.println("");
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {

            if (conn.getResponseCode() == 200) {
                System.out.println("here");

            }
        } catch (IOException e) {
            e.printStackTrace();
        }


    }

It is possible that the error ocurred because the receiving server closed the connection, maybe because your file exceeded the size limit. Have you tested with small files?
