Help HTTPS request doesn't work

[thomasmore72]

Hi,
I have been at this for 2 months (crying face).
This is my first time using Arduino so could be a very easy fix.
When this code is run it prints "Connection to GitHub lost" which from what I know just means it's not even connecting to the git file.

Here is the txt file : https://gist.githubusercontent.com/thomasmore72/b3ca747d9852fbe407a11e629d854f96/raw/28a9bccb6b4e0f4d163644063b5a092e29700ed0/gistfile1.txt

Like I said brand new to this so if you have a potential solution I might need a bit of code to understand :D

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

  // differentiat between 't'ext and image message
  if(messageMode[0] == 't'){
    oled.drawStringMaxWidth(0, 0, 128, message);    
  } 
  else {
    for(int i = 0; i <= message.length(); i++){
      int x = i % 129;
      int y = i / 129;

Hi,
did you solve this ?
the fingerprint where does it comes from?:)
