Перестало подключаться к базе

[Maray]

Добрый день!
Подскажите, пожалуйста. Создал базу данных в Azure. Пишу программу на С#, пытаюсь связаться с базой данных. Все работало, подключалось, отправляло запросы и т.д. А сейчас, спустя несколько часов работы, к базе данных нет подключения. Хотя я ни логин, ни пароль не менял. Подскажите, в чем может быть проблема

To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect.
