Can't get HTTP information

[Tipmanfrank]

This is maybe not directly related to Autoconnect but I hope you can help anyway.
I use AutoConnect to connect to internet.
I set up NTP time for Copenhagen.
I want to get information from homepage you can see from the Serial Monitor below.

The homepage returns "Demo klub".

I have an "Error code -5". What does this mean? Can you see what I have done wrong?

I have an "Error code -5". What does this mean? Can you see what I have done wrong?

Code on this page works: https://randomnerdtutorials.com/esp32-http-get-post-arduino/

So I need to change something in the code to make it work with Autoconnect. Hope that you plz can help a novice.

Error code: -5
I have an "Error code -5". What does this mean?

It is obvious that there is an error in http.GET(), which I think you are seeing as well. Since it is your code.
So your question about the meaning of the Error code, you can find it in the source code of the HTTPClient library.
https://github.com/espressif/arduino-esp32/blob/23d715af1b185fac21558c907af4ff5b86526aa4/libraries/HTTPClient/src/HTTPClient.h#L49

If you need more detailed information, specify a verbose Core Debug Level in the Tools menu of the Arduino IDE.

This error is not related to AutoConnect. You are issuing a request with HTTPS, but the code does not contain a certificate. BasicHttpsClinent.ino of ESP32 Arduino core's HTTPClient library has an example for applying the https. Before applying AutoConnect, I recommend following BasicHttpsClinent.ino example to experience how to apply HTTPClient over HTTPS.

Code on this page works: https://randomnerdtutorials.com/esp32-http-get-post-arduino/

That tutorial means little to nothing for the use case of using HTTPClient for HTTPS.

Fromm Stackoverflow I got an answer to change this:
WiFiClientSecure client;
HTTPClient http;
client.setInsecure();

Then it works. Thanks for your time.
