使用smack XMPP HttpFileUploadManager上传文件时出错

Question

文件上传不适用于localhost中的Openfire和Smack。我可以在本地主机上连接并登录，但是尝试使用HttpFileUploadManager上传文件时出现以下错误：

 failed to connect to 192.168.0.14 (port 7443): connect failed: ETIMEDOUT (Connection timed out)

简短的Android代码：

   HttpFileUploadManager httpFileUploadManager = HttpFileUploadManager.getInstanceFor(MainActivity.this.connection);

   File file = new File("/storage/3566-3936/DCIM/test.jpg");

   URL url =  httpFileUploadManager.uploadFile(file, new UploadProgressListener() {
              @Override
             public void onUploadProgress(long uploadedBytes, long totalBytes) {
                        Log.d("Progress:",uploadedBytes+"");
                  }
                }); 

HTTP文件上传插件也已添加到openfire服务器
