Error: Fetching the token failed: FIS_AUTH_ERROR even on Expo Client App

Hi guys, I hope you R doing well!

I have setup the expo notifications with Firebase and it was working very good!
But suddenly (after 2-3 days) I have problem with it!

The problem is that Notifications.getExpoPushTokenAsync() doesn’t return any token and I see the warning “Error: Fetching the token failed: java.util.concurrent.ExecutionException: FIS_AUTH_ERROR” in my terminal.

I have searched a lot but the other people’s problem is only when they are on their standalone app.
But my problem is even on Expo Client App, even when I use the example which is in Push Notifications Overview.

Even on a new project with “expo init new-app” I can’t get any push token from the Notifications.getExpoPushTokenAsync() !!

I will be very thankful if you can help me :slight_smile:
