Help with HTTPs on Wifimanager NodeMCU

Hello, my code is working fine if I disable the HTTPS on my website, I can send info to the page and receive it back on the NodeMCU, but when I activate the HTTPS and change the link on my code to HTTPS it just doesn't work and does nothing on the website.

Can someone help me to make my code work with HTTPS? I really have no clue why it is not working.

My code is the following:

#include <ESP8266WiFi.h>     
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266HTTPClient.h>

//WiFiManager

Install library WiFiClientSecure and Try to replace

#include <WiFiClient.h>

by

#include <WiFiClientSecure.h> 

check also the examples that come with WiFiClientSecure.

Hello, and thanks for your answer, I did tested yesterday replacing the wificlient by wificlientsecure but still had the same problem, I will give it another try today when I arrive home.

If you have access to the http server terminal, try to get tcpdump trace while sending the https request from the ESP8266. You can attach the trace to this post.
