first forgive me for my poor English,
I am having trouble connecting my ESP8622MOD with the actual database of the firebase.
The code compiles without errors by the arduino IDE but the data is not saved in the database. I have already tried to update libraries and everything that is possible.
Until a few days ago it was working, now it's gone.
Has anyone gone through this? Do you know how to help?
Thank you

em português:
Prezados, primeiramente me perdoe pelo meu péssimo inglês,
Eu estou com problemas para conectar meu ESP8622MOD com o Database real time do firebase.
O código compila sem erros pela IDE arduino porém os dados não são salvos no banco de dados. Já tentei atualizar bibliotecas e tudo o que é possível.
Até poucos dias atrás estava funcionando, agora não está mais.
Alguém passou por isso? sabe como ajudar?
Obrigado

#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>
#define FIREBASE_HOST "ldr-se...."
#define FIREBASE_AUTH "hErtyqjScrcF..."
#define WIFI_SSID "WIFI..."
#define WIFI_PASSWORD "97D124D.."
void setup() 
Serial.begin(9600);
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("conectando");
while (WiFi.status() != WL_CONNECTED) 
Serial.print(".");
delay(500);

Serial.println();
Serial.print("conectado: ");
Serial.println(WiFi.localIP());
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);

void loop() 
int sensorValue = analogRead(A0); // Ler o pino Analógico A0 onde está o LDR
float voltagem = sensorValue * (3.3 / 1024.0);
Serial.println(voltagem);
Firebase.pushFloat ("LDR", voltagem);
delay(5000);

This also happpen to me, my project have been working perfectly for 6 months non-stop until someday it stopped. I tracked it to be 1st of March, and I go and search for firebase in Google and found that they upgraded something inside firebase. That's probably why my project stopped working suddenly.

I went to this website and downloaded his library, everything is the same except the fingerprint, use the library included in the following website, my project is now working again.
