I get:
esp-sha: Failed to allocate buf memory
in ssl_client.c
probably due to the
WiFiClientSecure *client = new WiFiClientSecure;
run every loop without cleaning up with delete.

Hello and thank you for the great tutorial.
I have an issue with ESP32 causing a crash/reboot. It seems to be a memory leak eating heap in Secure Client block. Adding a delete client; after https.end(); fixed the problem.

I am using Arduino hardware package/library ESP32 – version 3.0.7.

Hello,
I had this project up and running for a couple of years but started to run into various problems with hosting companies and decided to take the project local using WAMP and MySQL installed and configured on a desktop computer over my home wifi network. I am using your updated files. I continue to receive http response error code -1 with no data being posted to the table. Can you suggest trouble shooting steps? Thanks!

When I run the mysite.com/esp-weather-station.php I see a white empty page…I removed the php code lines from the esp-weather-station.php file and leave only the html lines…Now I can see the page and the blank values..I checked the database name and password again, all is ok and right written.Do you have any idea what is wrong in the php lines?…Thanks..

Hello,
I tried to make this project with an esp32 and the same BME280 that is used in this tutorial.
I bought the BlueHost license, with the link present in this tutorial.
I thought I had succeeded in all the steps in this tutorial, but once the code had been uploaded to my esp32, the web page displayed a blank page.
In the previous steps, I managed to create the files “esp-post-data.php” and “esp-database.php”. I replaced the 3 fields indicated and obtained the following message: “No data posted with HTTP POST.”
But when I want to display the “https://example.com/esp-weather-station.php” page, the page remains blank and doesn’t display the diagrams shown in the tutorial, despite the fact that I’ve created the “esp-style.css” and “esp-weather-station.php” files.
Could you please help me? Thank you and have a nice day.
Sincerely

Hi Sara, Rui
Many thanks for the detailed post, I was able to modify this and have it routed through the blockchain on to my private fleet contract and allowed me to show a very secure esp32 demo.
