我有一个使用微软图形访问邮箱的应用程序。它可以在装有Windows 10的dev机器上运行。在服务器上，我得到了下面给出的错误。(Windows SERVER 2016和Windows SERVER 2012)
“系统.Net.Http.Http.HttpRequestException：发送请求时出错。->System.Net.Http.WinHttp异常：错误12002调用WINHTTP_CALLBACK_STATUS_REQUEST_ERROR，‘操作超时’。”

我一直在跟踪完全相同的问题，并发现我们的机器使用Netsh配置了一个代理，而代理服务器不可用。所以“操作超时”是100%有效的。
您可以通过从命令提示符调用“netsh winhttp show proxy”进行检查。我们的代理来自较旧的测试场景，因此我们只需在管理命令提示符下使用“netsh winhttp Reset Proxy”将其清除。
我认为这只是在升级Microsoft.Graph Nuget包后才在我们的服务器上崩溃的。也许它已经进行了“改进”，以遵循系统范围的代理服务器配置。
这也解释了为什么我不能让Fiddler跟踪用于Graph API调用，但它可以用于MSAL身份验证调用。
