简单的 C# Web 服务在本地工作，但不在服务器上工作

Question

我有一个C#网络服务，它非常简单，

我有使用外部 WSDL 的网络参考，

在公司计算机上本地工作，但在公司服务器上不工作。

我在其他帖子中看到这可能与代理有关，但是我已经厌倦了对有关代理的网络配置进行了一些不同的编辑，但我需要专家的帮助。

当我通过浏览器在服务器上运行时按调用时，我收到错误"无法连接到远程服务器"。

<?xml version="1.0" encoding="utf-8" ?>
<string xmlns="http://www.service-now.com/CatalogUpdateAutomationVariables">Unable to connect to the remote server</string>
