Authentication problem with Firebase

Question

I’m using Firebase for authentication and database of my app, everything was perfectly fine until (I’ll tell you exactly what happened because I don’t know if it has relation or not) I start to move the map that has the app, trying to implement a Placeautocompleteadapter, then I added such api and restricted access. When I saw Firebase had disconnected from the app, then I connected and did what he asked, but when I went to test the authentication gave this error

Basicnetwork.performRequest: Unexpected Response code 403 for

I can write in DB, only authentication that fails

 FirebaseAuth auth = FirebaseAuth.getInstance;

 //Ao clicar no botão de registrar
 auth.createUserWithEmailAndPassword(email, password){

 }
