Code:
                Dim HTTP
                Set HTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
                HTTP.setTimeouts 50000, 50000, 50000, 50000
                HTTP.Open "POST", sAddress, True
                HTTP.setRequestHeader "Content-Type", "multipart/form-data; boundary=" & ""
                'On Local Error Resume Next
                HTTP.send Data
                resp = HTTP.responseText
We have an old VB6 Project that we are updating.

After a client asked for changes, the above code stopped working

On the HTTP.send, we get "the data necessary to complete this operation is not yet available"

Been searching Google but can not find a good solution.
