The problem is no internet connection, your WiFi hotspot or router may not access to the internet.

You can test with other APs e.g. mobile hotspot.

Добрый вечер! А правила в базе данных правильно выставлены? База данных в тестовом режиме?

@Fantom-3000 The database rules are not applied when you authenticate with legacy token (database secret).
