httpupdate always Fails on Arduino IDE (modified default example)

[MG-Tawfeek]

Hardware:

Board: ESP32 Dev Module
Core Installation version: 1.0.4
IDE name: Arduino IDE?
Flash Frequency: 80Mhz
Computer OS: Ubuntu

Description:

Describe your problem here

Can't get the smallest Sketch in Arduino IDE for OTA update (from internet) to work
Always Errors
In Arduino IDE => Connection refused
HTTP_UPDATE_FAILED Error (-1): HTTP error: connection refused

in PlatformIO => The famous Stream Read Timeout !

Using IDF with the same link I'm putting below , OTA works , It's just Arduino Core

#include <Arduino.h>
#include <WiFi.h>
#include <HTTPClient.h>
#include <HTTPUpdate.h>

WiFiClient client;

static void InitWifi()
{
  Serial.println("Connecting...");
  WiFi.begin("wifi ssid", "wifi pass");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  //hasWifi = true;
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void setup() {
Serial.begin(115200);
InitWifi();
}

void loop() {

 t_httpUpdate_return ret = httpUpdate.update(client, "http://mymodbus.weebly.com/uploads/1/3/2/1/132175186/firmware.bin");
    // Or:
    //t_httpUpdate_return ret = httpUpdate.update(client, "server", 80, "file.bin");

    switch (ret) {
      case HTTP_UPDATE_FAILED:
        Serial.printf("HTTP_UPDATE_FAILED Error (%d): %s\n", httpUpdate.getLastError(), httpUpdate.getLastErrorString().c_str());
        break;

      case HTTP_UPDATE_NO_UPDATES:
        Serial.println("HTTP_UPDATE_NO_UPDATES");
        break;

      case HTTP_UPDATE_OK:
        Serial.println("HTTP_UPDATE_OK");
        break;
    }
}

Same problem here.
Probably related to the HTTPClient issue mentioned in #4039 and refers to #3347 , there is a workaround to HTTPClient, but i don't know if that can solve the update too.

[usane1]

The workaround is working with the update too.

Thank you for your reply
for some reason , as reported by many other users .. if you use a VPS , all goes fine
but with a shared hosting (cheap or free one) ., it usually fails .
I'll call this a FIX for the issue
Thanks again for your reply
