Check the security rules of your project. If you are using the default security rules that are created by firebase when you start your project, that might be expiring. You can either modify the expiration date in the rule ( Not recommended) or create some basic security rules like match /{document=**} { allow read, write: if request.auth != null; }

I am facing same issue as well from last 2 days.

I had the issue in the past and I just fixed it by adding some 10 trailing spaces in the end. Not sure if anyone has a better fix for this.

No data after July 9th for me as well.
