无法访问ParseServer中的音频文件

如何解决无法访问ParseServer中的音频文件

我从android应用程序上传了声音文件，以便其他用户可以访问它。但是它没有用，所以我在浏览器中打开了我的解析服务器。我收到了以下消息，因此无法下载音频文件：ERR_CONNECTION_REFUSED。我读到使用ParseFiles时应该配置publicServerURL。我在腻子中将其配置为ServerUrl，但仍然无法访问我的文件。我的错误在哪里？

我获取声音文件的代码如下：

ParseQuery<ParseObject> queryaudio = ParseQuery.getQuery("AudioFileClass");
                    queryaudio.whereEqualTo("GroupID",MainActivity.sharedPreference.getString("group",""));

                    queryaudio.addAscendingOrder("createdAt");


                    queryaudio.findInBackground(new FindCallback<ParseObject>() {
                        public void done(List<ParseObject> audioobjects,ParseException e) {
                            if (e == null) {
                                for (int a = 0; a < audioobjects.size(); a++) {
                                    Log.i("For","Ebene1");
                                    Date aktuelleZeit = Calendar.getInstance().getTime();

                                    if (printDifferenceMiliSecond(lastPlayed,audioobjects.get(a).getCreatedAt()) > 0 && printDifferenceSecond(audioobjects.get(a).getCreatedAt(),aktuelleZeit) < 30 && !audioobjects.get(a).get("UserID").equals(MainActivity.actuallyNetter.getObjectId())) // && !audioobjects.get(a).get("UserID").equals(MainActivity.actuallyNetter.getObjectId())
                                    {
                                        Toast.makeText(MapsActivity.this,"Sound wird abgespielt",Toast.LENGTH_SHORT).show();
                                        Log.i("If","Drin");


                                        ParseFile descr = audioobjects.get(a).getParseFile("audiofile");
                                        String audioFileURL = descr.getUrl();
                                        Log.i("URL",audioFileURL);
                                        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                                        lastPlayed = audioobjects.get(a).getCreatedAt();

                                        try {

                                            mediaPlayer.setDataSource(audioFileURL);
                                            mediaPlayer.prepare();
                                            mediaPlayer.start();
                                        } catch (IOException ex) {
                                            ex.printStackTrace();
                                            Log.i("Exception","Drin");

                                        }


                                    }
                                }


                            } else {
                                Log.d("score","Error: " + e.getMessage());
                            }
                        }
                    });

我的解析服务器看起来像这样= ParseServer
