android - 无法建立与 Firebase 实时数据库的连接

Question

我们正在尝试更新我们的 firebase 实时数据库，但更新失败且没有任何回调。使用我们的 android 应用程序的设备很少发生这种情况，我能够在 logcat 中发现这些设备的 firebase 连接失败。

这些日志是使用以下方法生成的： FirebaseDatabase.getInstance().setLogLevel(Logger.Level.DEBUG); 然后被写入文件。

在网上搜索这些日志，我得到了一些提示

1. android 设备可能已植根
2. 火力基地问题
3. 防火墙/安全问题
4. 网络提供商问题

但是我们无法知道相同的确切根本原因。

谁能提供一些见解或解决方案来解决这个问题？

下面附上日志。
