Fails in connecting to api.pushbullet.com

.........
Connected to MY-SSID
IP address: 192.168.0.113
Pushbullet note pushing
connecting to api.pushbullet.com
connection failed

Please help me get past this. I am unable to figure out why this is happening. Here is my code:

#include <ESP8266WiFi.h>
#include <PushbulletAPI.h>

// wifi connection variables
const char* ssid     = "ssid";
const char* password = "pwd";

boolean wifiConnected = false;

int incomingByte = 0;
boolean connectWifi();

PushbulletAPI pb = PushbulletAPI("my key");


void setup() {
  // Initialise Serial connection
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT); 

  // Initialise wifi connection
  wifiConnected = connectWifi();

  
}

void loop() {
  // check if the WiFi connection were successful
  if (wifiConnected) {
          Serial.println("Pushbullet note pushing");
          pb.notify("Write the title here","Write the body here");  
          
      }
    }
 

// connect to wifi – returns true if successful or false if not
boolean connectWifi() {
  boolean state = true;
  int i = 0;
  WiFi.begin(ssid, password);
  Serial.println("");
  Serial.println("Connecting to WiFi");

  // Wait for connection
  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
    if (i > 10) {
      state = false;
      break;
    }
    i++;
  }
  if (state) {
    Serial.println("");
    Serial.print("Connected to ");
    Serial.println(ssid);
    Serial.print("IP address: ");
    Serial.println(WiFi.localIP());
  }
  else {
    Serial.println("");
    Serial.println("Connection failed.");
  }
  return state;
}

Adding client.setInsecure(); on PushbulletAPI::PBConnect() did the trick for me.
