firebase-arduino: Arduino board (node mcu) is not sending or read any data to firebase

My project worked perfectly until 2020/02/17 1:28:55 AM and suddenly it crashed. error - firebase failed there is no issue with wifi or the Node MCU libraries I used - firebase library : https://github.com/FirebaseExtended/firebase-arduino JSON library : https://github.com/bblanchon/ArduinoJson/tree/v5.13.1

Please help me and thank you for your time.

This is my demo code:

`#include <ESP8266WiFi.h> #include <FirebaseArduino.h>

// Set these to run example. #define FIREBASE_HOST “xxxxxxxxxx.firebaseio.com” #define FIREBASE_AUTH “xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx” #define WIFI_SSID “wifi” #define WIFI_PASSWORD “wifipwd”

void setup() { Serial.begin(9600);

// connect to wifi. WiFi.begin(WIFI_SSID, WIFI_PASSWORD); Serial.print(“connecting”); while (WiFi.status() != WL_CONNECTED) { Serial.print(“.”); delay(500); } Serial.println(); Serial.print("connected: "); Serial.println(WiFi.localIP());

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); }

int n = 0;

void loop() { // set value Firebase.setFloat(“number”, 42.0); // handle error if (Firebase.failed()) { Serial.print(“setting /number failed:”); Serial.println(Firebase.error());
return; } delay(1000);

// update value Firebase.setFloat(“number”, 43.0); // handle error if (Firebase.failed()) { Serial.print(“setting /number failed:”); Serial.println(Firebase.error());
return; } delay(1000);

// get value Serial.print("number: "); Serial.println(Firebase.getFloat(“number”)); delay(1000);

// remove value Firebase.remove(“number”); delay(1000);

// set string value Firebase.setString(“message”, “hello world”); // handle error if (Firebase.failed()) { Serial.print(“setting /message failed:”); Serial.println(Firebase.error());
return; } delay(1000);

// set bool value Firebase.setBool(“truth”, false); // handle error if (Firebase.failed()) { Serial.print(“setting /truth failed:”); Serial.println(Firebase.error());
return; } delay(1000);

// append a new value to /logs String name = Firebase.pushInt(“logs”, n++); // handle error if (Firebase.failed()) { Serial.print(“pushing /logs failed:”); Serial.println(Firebase.error());
return; } Serial.print(“pushed: /logs/”); Serial.println(name); delay(1000); }`
