Error Connecting the ESP32 to the Firebase!! Hep

Could anyone help me to review the code where i am creating home automation project using Firebase database and Esp32 4channel relay module.

The problem is your network.

That library is deprecated and no further support.

You should learn how to use the library correctly by following its examples.
