Android 离子超时将文件发送到sails（skipper）

我的情况是，当我用Ion在Android中向我的Sails服务器发布一个jpg文件时，它超时了。这是我的密码：

安卓：

Ion.with(ctx, URLConstant.getURL(URLConstant.URL_TYPE_UPLOAD_AVATAR))
            .setMultipartFile("avatar", new File("assets/avatar.jpg"))
            .asJsonObject()
            .setCallback(new FutureCallback<JsonObject>() {
                @Override
                public void onCompleted(Exception e, JsonObject result) {
                    if (e != null) {
                        System.out.println("Upload file error.");
                        e.printStackTrace();
                        return;
                    }
                    System.out.println("Upload file done");
                }
            })

服务器与POSTMAN配合良好，但与Ion配合不好，“开始上载文件”已记录，但未“上载完成”，最终我在客户端收到TimeOutException，如下所示：

谁能给我一点线索吗。致以最良好的祝愿
