Can't get HTTP information #565

Closed Tipmanfrank closed 1 year ago

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.

Code: `

The homepage returns "Demo klub".

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.
