I ran into such a problem, when I tried to initialize firebase and get the FCM token, I get this error, who faced it? What could be the reason? A month ago, everything worked, after that nothing was changed in google-services.json file, firebase flow in project, or in google console.
API key permissions added
In our case, this happened when we added a new Firebase library to our project (Performance Monitoring). Our API key is restricted to only allow certain APIs to work, as suggested by Google.
Log in to the Google Cloud Console, and make sure you're allowing the API to work with your restricted key. In this specific case, you need to allow the Firebase Installations API.
Once I added that and waited about 10 minutes, this error stopped and the Firebase tools are working as expected with our app.
The problem was on key, idk why, but when I set new key, all ok.
20.05.2022 Better to use Android apps restrictions now.
