Thanks for this tutorial, was excactly what I was searching for. Keep up the good work lad

A great job. Thank you very much.
You show difficult topics in a simple way that everyone can better understand it and learn it faster. There are not many examples in books. They are usually too complicated for novices and hobbyists. You are doing a very good job, making the world better. God bless you! Maybe someday I will be able to repay you for this lesson - I hope. Best Regards.

Hi, how do I get data from the ESP32 to show on a website? Is the post method also the right way? Cause I get the right payload back but no data is shown on the webpage!

Please i need to send data to node js server from esp32 i’m stuff

90% of the time it posts successfully. Other 10% of the time is shows http error -1. How do I fix this issue?
I have tried with and without persistent connection. The issue still exists.

Another thing is that sometimes it takes upto 10sec to get a http response code, even when I set the http timeout to 2 sec. How do I stop the request if no response is received within 2 seconds? I have tried using millis() method but since the http.post is blocking, it doesn't work.

Did you experience these issues? If yes how did you fix them?
