.NET Business Connector for Dynamics AX ошибка подсоеденения

[Deza]

Соединяюсь C#

NetworkCredential myCred = new NetworkCredential("u46874", "p@ssw0rd", "soa.net");
ax.LogonAs("u46874", "soa.net", myCred, null, null, "Ax-test@ax-apl:2725", null);

Локально все работает отлично, при публикации на веб сервер выдает ошибку

Microsoft.Dynamics.BusinessConnectorNet.BusinessConnectorInstanceInvalid:   Business Connector     AOS,   .

в чем может быть причина
