肥皂服務在VS中有效，但在IIS中無效

Question

我有WCF應用程序中使用的第三方SOAP Web服務

在Visual Studio中運行並使用WCF調試器時，該服務運行良好，但是在完全IIS中運行時，它將出現以下錯誤

System.ServiceModel.EndpointNotFoundException
There was no endpoint listening at https:// ***.custhelp.com/cgi-
bin/ ***.cfg/services/soap This is often caused by an incorrect address or 
SOAP action. See InnerException, if present, for more details. ---> 
System.Net.WebException: Unable to connect to the remote server ---> 
System.Net.Sockets.SocketException: An attempt was made to access 
a socket in a way forbidden by its access permissions 74.117.207.64:443

我知道該服務會阻止TLS 1.0，因此我將ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11（和... | Tls12）放在一起

我已經確認它們都在64位模式Environment.Is64BitProcess = true中運行

我也曾嘗試在WebApi應用程序中使用相同的肥皂服務，但出現相同的錯誤。
