angular - 从真实设备尝试时，Ionic 5 firebase 给出错误 net::ERR_NAME_NOT_RESOLVED。从网络浏览器工作正常

Question

我正在使用 ionic 5 和 firebase 实时数据库。我创建了一个应用程序，该应用程序在从 firebase 获取时运行良好，但在从 android 设备运行时会失败。

错误说：

https://myapp-30w4w-default-rtdb.asia-southeast1.firebasedatabase.app/.lp?start=t&ser=69072188&cb=1&v=5&p=1:3805195994626:web:6d4rg6yu06e0a2dce9e1b&ns=myapp-30f3f-default-rtdb网： :ERR_NAME_NOT_RESOLVED

下面是 package.json 依赖项

      },
      "cordova-plugin-ionic-keyboard": {}
    },
    "platforms": [
      "android"
    ]
  }

Firebase 数据库规则是：

{
  "rules": {
      ".read": true,
      ".write": true
  }
}

从 chrome 浏览器一切正常，但在 android 上运行应用程序时相同，它给出了上述错误。从浏览器中，我可以从 firebase 但不能从 android 应用程序中保存和获取记录。这是一些火力限制还是什么？
