Everything was working fine before but now firebase can't seem to create a new token. I'm trying to call await FirebaseMessaging.instance.getToken(); but getting this error


FLTFirebaseMessaging: An error occurred while calling method Messaging#getToken, errorOrNil => {
    NSLocalizedFailureReason = "Too many server requests.";
}
[VERBOSE-2:ui_dart_state.cc(199)] Unhandled Exception: [firebase_messaging/unknown] An unknown error has occurred.
#0      MethodChannelFirebaseMessaging.getToken (package:firebase_messaging_platform_interface/src/method_channel/method_channel_messaging.dart:226:7)
<asynchronous suspension>

<asynchronous suspension>
#2      _SignUpState.build.<anonymous closure> (package:shuri_parent/src/pages/sign_up.dart:252:43)

Oh! my bad, I found the issue. My issue was a wrong api key of firebase in the GoogleServices-info.plist file

Thanks for all the support you gave me.

This issue is caused by limited permission to your api key from Google cloud console, here are steps that fixed my issue,

  1. Login to Google cloud console and select your current project

  2. Select **API Credentials - APIs & Services ** or IAM Permissions on left sidebar.

  3. Select iOS key(auto created by firebase)'s menu on right if you have selected **API Credentials - APIs & Services **

  4. Select Edit API key

  5. Under Selected APIs: dropdown menu select these options, Firebase Installation API Firebase Cloud Messaging API FCM Registration API

I resolved this issue by redownloading the GoogleService-Info.plist from the firebase & replace the current file.

Doesn't works for me :( – Overscrupulous
this will work . – Panties
In Firebase, go to Project (iOS) -> click gear icon -> Apple apps -> click download of GoogleService-Info.plist – Thrombokinase

in my case I have different bundle identifier on Xcode and in Firebase Console.

I have this issue after implementing Flavor on Flutter app. the Bundle Identifier is created dynamically based on the scheme on my Xcode

Make sure that your Flutter app targets iOS 8 or later. Please check this link below

https://firebase.google.com/docs/flutter/setup?platform=ios

in some android and ios devices not receiving firbase base responce because of its versions and api level

Yes it has target IOS 10.0, Befor It was working fine in production until it started showing that error only on getToken() on users mobile phones. – Stutsman

In my case, i was using a different bundle id in debug and profile, and the key under APIs & Services => Credentials => iOS key (could be 2 keys, auto created by Firebase and auto created by Google Service) was set to iOS app restriction using the release bundle id, so, you need to add your debug bundle id here in the restrictions.

Turn out the error throw because I'm using a vpn app. Try to change your network to a different network then try again
