I am trying to understand the TLS verify of the this example: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/HTTPSRequest/HTTPSRequest.ino#L30
Do I understand it right that every time the server renews his certificate, I need to find out the new fingerprint and adjust the fingerprint in the code? Or do I have to change the fingerprint only if it is a completely new cert?
Thanks in advance,
Henry
