Ionic Firebase登录问题

Question

I have an ionic 1 application and I am getting a weird error on log in only on android. Only the first time when the user opens the application and logs in, It is logging perfectly. When he logs out and tries to log in again I am getting this error "Auth/Network-Request Failed" and cannot login unless he closes the application and reopens. I do not get whats the issue and why the first time it is working. This is my code.

<ion-content style="background-image:url(img/LoginBack.jpg); background-size:100% 100%;" ng-controller="LoginController">

    <hr style="height:100px; visibility:hidden">
        <div align="center">

            <img src="img/loggo.png" style="width:43%;height:13vh">

//JS FILE firebase.auth().signInWithEmailAndPassword($scope.registerusername, $scope.registerpassword) .then(function (user){ //GO HOMEPAGE }) .catch(function (error) { alert(errorCode);
});

Answer 1

did you use this method on signout?

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