API геолокации не работает на NodeMCU ESP8266

Question

Я использую nodemcu-esp8266 для получения координат местоположения с помощью API геолокации. Прочитав и попробовав много ссылок, моя программа все равно не работает. Вот полученный ответ:

Может кто-нибудь объяснить, почему программа не работает?

спасибо
