尝试登录时反应本机，Firebase网络错误

Question

I've followed a React-native login tutorial using Firebase, I use create-react-native-app for easy dev(my package.json ), I'm using NodeJS v6.10.1 , I'm using Note 4 Device(4.4.4), I enabled Email/Password authentication within Firebase console, for some reason I get:

{
    code: "auth/network-request-failed",
    message: "A network error (such as timeout, interrupted connection or unreachable host) has occurred."
}

I didn't forgot to use firebase.initializeApp and my code is:

firebase.auth().signInWithEmailAndPassword(email, password)
.catch(e0 => {
  console.log(e0);
  firebase.auth().createUserWithEmailAndPassword(email, password)
    .catch(e1 => {
      console.log(e1);
      this.setState({ error: 'Authentication Failed.' });
    });
});

For both I get the same error object.

Answer 1

So the problem was:

It all starts by this Debugger and device times have drifted by more than 60s , due to other, adb related problem I couldn't run adb shell "date -s date +%m%d%H%M%Y.%S " , after I fixed my adb problem I run adb shell "date -s date +%m%d%H%M%Y.%S " , now the Firebase error was saying: such as timeout , adb(my computer) time was -4min than the device, so to fix that I changed the time on my computer, adding 4min so it will match the device time.

What I assume was the problem, I'm not a networks expert so please if anyone can fix some of my assumptions if there is something wrong:

For explanation I just use unreal stuff( reqTimestamp ,...), but the concept is valid(I hope):

The device signed the request with a timestamp and a timeout, for example, reqTimestamp= 22:16 , reqTimeout= 22:17 , my device is connected throught my wifi, so when the modem connected to my computer, a basic check on my computer or internally the modem, such as: if(reqTimeout > timeNow) reject , could prevent the request from even leave my network so Firebase issue this generic error regarding network problem.

Answer 2

I was getting this same error for a react-native project running using expo on an android device emulator(on windows).

I know this will sound weird but in my case I was getting this error when using internet from my phone's hotspot. When I switched to my normal wi-fi internet connection, the error went away.

Hope this helps.

Answer 3

I have the same error. In my case it caused by more then one identifier for the same email in Firebase -> Authentication. Do not know why I have more than one record for the same email, but after deleting all and login again. The problem is resolved.

Answer 4

I had the same issue. I connected to a VPN, the error went away.
