InfoPath published to https cannot access web service

[Aidan]

I have an InfoPath form that is fully trusted published to an https
SharePoint site collection.

The InfoPath form project contains a reference to a class library that
connects to some web services.

On load the form tries to populate some fields from the web services but the
call to the web service from the class library fails.

When exactly the same form is published to a site collection in the same
farm using http the connection is made and the form populates successfully.

We have tried putting the web services over https and http but both produce
the above result.

Does anyone have any ideas what is causing this or how it can be resolved?

4.Click Add button. Enter the https urls, webservice urls and then click ok.
