Azure Postgres：主机“ 0.0.0.0”，用户“ UserName”，数据库“ orders”，SSL上没有pg_hba.conf条目

Question

我有一个正在开发中的Azure网站，可连接到新的Azure Postgresql数据库。

这个错误似乎是在周末开始的。上次我上周五尝试时，它运行良好。我的Azure网站计划的IP地址似乎已更改，因此我编辑了Azure Postgres防火墙规则。

真正奇怪的部分是“ 0.0.0.0”主机。Web服务器对数据库的IP地址为“ 0.0.0.0”的样子如何？我确实也向防火墙添加了“ 0.0.0.0”，但这没有任何效果。我当然不能直接在Azure上编辑pg_hba.conf文件。

另外，从我的开发计算机运行时，它也可以正常工作。我尝试重新部署我的网站，没有任何乐趣。

这是完整的堆栈跟踪：
