Hi, i need help with my project, im trying to upload de latitude and longitude of my NodeMCU ESP8266 to a realtime database and i dont know why im not able to connect with firebase. Could someone help me please? i need to finish this project soon. Im gonna upload de code and the file also. Appreciate any help
