Hello I am trying to make a request using WiFiEsp library but even the examples not working, I have searched a lot but never solved it. most of the solutions are outdated and do not solve anything, I am using Arduino Mega 2560 and ESP8266 the problem as shown in the log is that it's not connected to google.com and I have tried my APIs and I got the same response.
code:
/*
WiFiEsp example: WebClient
This sketch connects to google website using an ESP8266 module to
perform a simple web search.
For more details see: http://yaab-arduino.blogspot.com/p/wifiesp-example-client.html
