ESP8266 not working on https correctly

[rego0116]

Hi everyone! I'm trying to use WiFiClientSecureBearSSL library, but when I try to access my website, and make a post request there, I get a 308 code. I have modified that part of the code from http to https, but I still get that error. This is the code:

void sendSensorData() {
  // Check if WiFi is connected
  if (WiFi.status() == WL_CONNECTED) {
    WiFiClient client;  // Create a WiFiClient object

    // Initialize the HTTPClient object with the server's URL
    HTTPClient https;

    https.begin(client, "https://" + String(serverIP) + ":" + String(serverPort) + "/insert_data.php");

    // Set headers for the HTTP request
    https.addHeader("Content-Type", "application/x-www-form-urlencoded");

    // Construct the POST data
    String postData = "api_key=2023ESPCHARTER";
    postData += "&sensor_name=Sensor1";
    postData += "&location=Living Room";
    postData += "&temperature=" + String(random(20, 30));
    postData += "&humidity=" + String(random(40, 60));
    postData += "&pressure=" + String(random(980, 1030));
    postData += "&reading_time=2023-07-28 10:00:00";

    // Perform the HTTP POST request
    int httpResponseCode = https.POST(postData);

    // Display status on OLED screen
    display.drawXbm(0, 0, 128, 64, image_data_wifiConnected);
    display.setFont(Open_Sans_Regular_10);
    display.drawString(80, 1, WiFi.localIP().toString());
    display.drawString(110, 50, String(httpResponseCode));
    display.setFont(Open_Sans_Regular_12);
    display.drawXbm(0, 0, 128, 64, image_data_snowflake);
    display.display();
    display.clear();

    // Check the HTTP response
    if (httpResponseCode > 0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    } else {
      Serial.println("Error in HTTP POST request");
    }

    // Close the HTTP connection
    https.end();
    ip = WiFi.localIP().toString();
  }
}
