Hello Sir,
I'm using your firebase library(ESP8266) but I'm facing a problem even my friends are also facing the same problem. Actually, this library isworking perfectly only up to 1 hrs after that it's not working, it's not able to receive/post data showing connection lost.

I am getting this error after 1 hour of continuously using it. Please have a look.

You should follow the examples.

This example comment is already stated about Firebase.ready

Firebase-ESP8266/examples/Basic/Basic.ino

Lines 134 to 139 in 1ec1e88

	void loop()
	{
	// Firebase.ready() should be called repeatedly to handle authentication tasks.
	if (Firebase.ready() && (millis() - sendDataPrevMillis > 15000 || sendDataPrevMillis == 0))

Don't send or read the data from database repeatedly like that because your data bandwidth quota may be limited soon, or charge with expensive cost.
