Umbraco.Core.Exceptions.BootFailedException：已配置连接字符串，但Umbraco无法连接到数据库

Question

[具有Umbraco经验和Azure的人，我在azure上托管了umbraco的网站，它最初运行良好，但是现在出现此错误，我已经阅读了几乎所有与此相关的文章，但实际上我找不到解决方案当我在本地运行该项目时，它可以正常工作并且可以很好地连接到Azure SQL服务器和数据库，但是在托管之后，使用版本8.1.2会在我下面抛出异常：

如果您在Azure门户中使用面向Umbraco的Azure应用服务，请确保您的数据库防火墙设置的“允许Azure服务和资源访问此服务器”设置为“是。
