Azure Function运行失败，提示‘用户名或密码不正确’求助

浏览器访问Azure Function App URL时突然弹出「用户名或密码不正确」错误，已完成以下排查：

• 确认WEBSITE_CONTENTAZUREFILECONNECTIONSTRING与AzureWebJobsStorage使用同一存储账户
• 近期未对该Function App执行部署操作

目前无法通过Kudo/控制台获取问题详情，应用服务编辑器访问返回Internal Server Error，尚未定位根因。

环境与应用设置 #

该Azure Function基于.NET 6、C#开发，应用设置详情如下：

关联存储账户近期配置变更 #

近期对Function App关联的存储账户执行了以下配置修改：

• 将复制操作允许范围从「任意存储账户」改为「同一Azure AD租户内的存储账户」（路径：存储账户→配置）
• 将文件共享安全配置从「最大兼容性」改为「最高安全性」（路径：存储账户→文件共享→最高安全性）
• 取消勾选存储账户对象复制高级设置中的「跨租户复制」选项
• 启用存储账户软删除功能
