HTTPS路由问题

Question

我们似乎遇到了错误路由HTTPS呼叫的问题：

在本地测试时，对api.dotmailer.com:443的应用程序调用工作正常（通过服务引用）;

然而，当发布到我们的实时服务器时，所有https调用都被路由到应用程序域mydomain：443而不是api.dotmailer.com。

初始化服务客户端的实例时，它会毫无例外地退出。

以下是相关代码：

 If Branchsettings.Email & Branchsettings.Password <> Nothing Then
        Response.Write("<script language='javascript'>alert('Contact object: " & "Flag 1" & "');</script>")

        If Branchsettings.Email & Branchsettings.Password <> "" Then
            Response.Write("<script language='javascript'>alert('Contact object: " & "Flag 2" & "');</script>")
            Dim username As String = Branchsettings.Email
            Dim password As String = Branchsettings.Password
            Try

                Dim addressBookID As Integer = 2841982
                dataTable = GeLandlord.GetLandlordsByPortalBranchID(siteLogin.GetPortalBranchID(Context.User.Identity.Name), True, True)
                Dim contact As New dotmailer.ApiContact
                Dim cdata As New dotmailer.ApiContactData
                Response.Write("<script language='javascript'>alert('Contact object: " & "Flag 3" & "');</script>")
                Try
                    api = New dotmailer.ApiServiceClient
                Catch ex As Exception
                    Response.Write("<script language='javascript'>alert('Contact object: " & ex.ToString & "');</script>")
                End Try

有谁知道导致这个问题的原因是什么？
