Что делаю не так?

Здравствуйте.
Включите логирование уровня ALL, как тут и приложите лог.

А если закомментировать

Я бы подумал, что ошибка на стороне сервера. Но если производить вызов через CSP, код отлично работает

Set oXMLHTTP = CreateObject("Microsoft.XMLHTTP")

Set oXMLDoc = CreateObject("MSXML2.DOMDocument")


Call oXMLHTTP.Open("POST", "https://test-api.express-gate.ru:2003/orders.svc", False)


Call oXMLHTTP.setRequestHeader("Content-Type", "text/xml; charset=utf-8")
Call oXMLHTTP.setRequestHeader("SOAPAction", "http://dev.triasoft.com/contracts/IOrderService/GetAllOrders")

Call oXMLHTTP.setRequestHeader("Content-Length", "length")

st = "<?xml version=""1.0"" encoding=""utf-8""?> <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema""> <soap:Body> <GetAllOrders xmlns=""http://dev.triasoft.com/contracts"" /> </soap:Body> </soap:Envelope> "

oXMLHTTP.send st

Debug.Print oXMLHTTP.responseXML.XML

При запросах без прокси (напрямую), ответ тот же.
