com.jcraft.jsch.JSchException: timeout: socket is not established

I am trying to upload a file to a server (with java) where I have an acount and the SFTP connection stopped working (for a timeout problem I guess). I want to know is there a way to reset this connection and get it working. This is the function:

    public static void upload(File file, boolean retry) {
    try 
    {
        System.out.println("Uplodaing file " + file.getName());

        JSch jsch = new JSch();
        Session session = jsch.getSession("****", "*****", 22);
        session.setPassword("*****");

        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.setTimeout(5);

        System.out.println("Establishing connection");
        session.connect(10);


        Channel channel = session.openChannel("sftp");
        channel.connect();
        ChannelSftp sftpChannel = (ChannelSftp) channel;

        if (!retry)
            sftpChannel.put(file.getAbsolutePath(), file.getName(),new SystemOutProgressMonitor(), ChannelSftp.OVERWRITE);
        else
            sftpChannel.put(file.getAbsolutePath(), file.getName(),new SystemOutProgressMonitor(), ChannelSftp.RESUME);

        channel.disconnect();
        session.disconnect();
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
        upload(file, false);
    }

}

I know this question is quite old but in case anyone stumbles over it (as I did): The problem is the connection timeout, which should be in milliseconds. In case OP intended 10 seconds, it should be 10000 here. 10 milliseconds simply isn't enough.
