Same problem here!

[doublecookie]

Solved it. Works if you change esp8266 board manager from 3.0.0 back to 2.7.4 seems like this library hasnt been adapted to the new ESP8266HTTPClient version

[Diere1]

@doublecookie thank you, got the job run succesfully.

[Diere1]

I got some new problem, after uploading, this lines appear in serial monitor.
