Send Request Failed (Firebase & ESP8266)

[AdleeAfif]

Hello and hi, I was doing my project for 2 weeks already and suddenly last night I got this problem:

However, it does seem to send the data sometimes:

Here's my code:

#include <SFE_BMP180.h>
#include <Wire.h>
#include "FirebaseESP8266.h"
#include <ESP8266WiFi.h>
#include "DHT.h"
#include <NTPClient.h>
#include <WiFiUdp.h>

DHT dht(D3, DHT11);
SFE_BMP180 bmp;
double T, P;
char status;
WiFiClient client;


#define FIREBASE_HOST "weathereye-####-default-rtdb.firebaseio.com"
#define FIREBASE_AUTH "Jd522#######C3gVwbaCCTNRiDwdmEmwcOdm8"

const char *ssid =  "Tenda-001C92";
const char *pass =  "89172731";
const char* server = "api.thingspeak.com";

FirebaseData firebaseData;
FirebaseJson json;

const long utcOffsetInSeconds = 28800;
//----------------------------------------Define NTP Client to get time
WiFiUDP ntpUDP;
NTPClient timeClient(ntpUDP, "pool.ntp.org", utcOffsetInSeconds);

void setup() {
  Serial.begin(115200);
  delay(10);
  bmp.begin();
  Wire.begin();
  dht.begin();
  WiFi.begin(ssid, pass);


  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}

void loop() {

  //Get time from the internet and format the display.
  timeClient.update();
   String hr, mn, sc;
   if (timeClient.getHours() < 10) {
      hr = "0" + String(timeClient.getHours());
    }
   else {
      hr = String(timeClient.getHours());
    }
    
   if (timeClient.getMinutes() < 10) {
      mn = "0" + String(timeClient.getMinutes());
    }

      mn = String(timeClient.getMinutes());
    }

    }

  String currentDate = String(monthDay) + "-" + String(currentMonth) + "-" + String(currentYear);
  
  //BMP180 sensor
  status =  bmp.startTemperature();
  if (status != 0) {
    delay(status);
    status = bmp.getTemperature(T);

    status = bmp.startPressure(3);// 0 to 3
    if (status != 0) {
      delay(status);
      status = bmp.getPressure(P, T);
      if (status != 0) {

      }
    }
  }

  //DHT11 sensor
  float h = dht.readHumidity();
  float t = dht.readTemperature();

  if (isnan(h) || isnan(t)) {

Your internet is not reliable.

You should set the debug options in Arduino IDE to get the debug info of your WiFi and BearSSL.

Yep that seems to be the reason why. Whew, thanks a lot sir!
