Not Connecting with OCPP server

[VjSargunam]

Hi Matt, As per the instruction i installed the ArduinoOcpp in to ESP32. The project got successfully built. But after uploading the code to esp32 it is not connected with the central server it give be warnings as shown below in the serial terminal window. [main] Wait for WiFi: ... connected! [AO] info (.pio/libdeps/esp32dev/ArduinoOcpp/src/ArduinoOcpp/Core/Configuration.cpp:103): init new configurations container on flash filesystem: /volatile

Can you please explain me what is the above message is all about,

Here is my code

#include <Arduino.h>
#include <WiFiClientSecure.h>
#include <HTTPClient.h>
#include <Update.h>
#include <FS.h>
#include <ArduinoOcpp.h>

#define STASSID "username"
#define STAPSK  "password*"

#define OCPP_HOST "echo.websocket.events" // I added my own hot address here
#define OCPP_PORT 80
#define OCPP_URL "ws://echo.websocket.events/"

void setup() {
    Serial.begin(9600);
    Serial.setDebugOutput(true);
    Serial.print(F("[main] Wait for WiFi: "));

    WiFi.begin(STASSID, STAPSK);
    while (!WiFi.isConnected()) {
        Serial.print('.');
        delay(1000);
    }

    Serial.print(F(" connected!\n"));

    //Initialize the OCPP library

    OCPP_initialize(OCPP_HOST, OCPP_PORT, OCPP_URL);

    //Notify the Central System that this station is ready

    bootNotification("DC-001", "Company name", [] (JsonObject confMsg) {
        //This callback is executed when the .conf() response from the central system arrives
          Serial.print(F("BootNotification was answered. Central System clock: "));
          Serial.println(confMsg["currentTime"].as<String>()); //"currentTime" is a field of the central system response

        //Notify your hardare that the BootNotification.conf() has arrived. E.g.:
        //evseIsBooted = true;
    });

}

void loop() {
  // put your main code here, to run repeatedly:
}

And here is the compilation messages in the terminal

were you able to connect to ocppp server
