The database URL (actually only host name) may not valid.

Line 18 in a74d6e4

#define DATABASE_URL "URL" //<databaseName>.firebaseio.com or <databaseName>.<region>.firebasedatabase.app

I can confirm that this is not library issue.

If you have tried everything in your code and all credentials you provided are ok. You should check your internet connection included your WiFi AP, router and internet ISP.
