Android Ionic firebase登录问题

我有一个ionic 1应用程序，我只在android上登录时出现了一个奇怪的错误。只有当用户第一次打开应用程序并登录时，它才能完美地登录。当他注销并尝试再次登录时，我收到错误“Auth/Network Request Failed”，除非他关闭应用程序并重新打开，否则无法登录。我不明白这是什么问题，为什么它第一次起作用。这是我的密码

使用Facebook登录
已经有账户了吗？登录


登录
或
通过电子邮件注册
忘记密码了？

//JS文件 firebase.auth（）.signInWithEmailAndPassword（$scope.registerusername，$scope.registerpassword） .then（功能（用户）{ //GO主页 }) .catch（函数（错误）{ 警报（错误代码）；

---

});

您在注销时是否使用了此方法

firebase.auth().signOut().then(function() {
 // Sign-out successful.
}, function(error) {
 // An error happened.
});

Firebase Auth使用

navigator.onLine

检测网络状态。如果此问题偶尔发生，可能与

navigator.onLine

有关。尝试安装可修复

navigator.onLine

问题的软件。
