我有一个集成项目，我的 RestAPI 调用其他项目的 WCF 服务来执行一些 CRUD 操作。
我的项目基于 .net 核心 2.2.102 构建。我在 BETA 环境中部署了我的项目(在我的例子中是 PROD(，并指向 WCF 服务的 PROD URL。然后我在尝试从我的应用程序运行请求时收到此错误：无法建立 SSL 连接，请参阅内部异常。
我试图在我的本地重现它。 但是当我指向 WCF 服务的 BETA URL 时，它在本地计算机上工作正常。我检查了防火墙设置。我可以看到这些都很好。
可能的根本原因是什么？我无权访问 BETA，因此无法使用试错方法进行部署。我正在附加内部异常堆栈跟踪。

这应该会弹出一个对话框，询问您是否要将证书添加到受信任的存储区，您显然应该接受该存储区。您需要为每个项目执行此操作。例如，如果 Web 应用连接到 API 应用，则仅信任该 Web 应用是不够的。您需要对 API 应用执行相同的操作，以便信任两个证书。
