I am trying to connect signin into my app, i am getting this error

W/System  (14618): Ignoring header X-Firebase-Locale because its value was null.
I/flutter (14618): Login Error:: [firebase_auth/unknown] com.google.firebase.FirebaseException: An internal error has occurred. [ Chain validation failed ]

Last week i dint have any issue in sign in, i have no idea y i got this suddenly , i even changed the google-services.json file.

Can anyone help on this issue, i don’t have any issue while connecting in real device(android)

check you internet connection, Firebase needs stable connection and rebuild the project again. if this is not working, share some code.
