'The data necessary to complete this operation is not yet available VBA runtime error

I'm getting this runtime error 2147483638 from excel vba code editor. I'm trying to send to my web service xml string and get a response back from the web service. Seems like it errors out because the response is "". Here's my code:

...... 
OutboundDocument.LoadXML (XMLServiceString)
On Error GoTo DoThisAgain
    XMLHTTPClient.Open "POST", WebServiceURL, False
    XMLHTTPClient.Send (OutboundDocument)
   'errors out here

DoThisAgain:
    serviceResponse = XMLHTTPClient.ResponseText ' equals "" gets error

vba

Solution 1:^[1]

This can avoid the error:

Dim MyRequest As MSXML2.XMLHTTP
Set MyRequest = CreateObject("MSXML2.XMLHTTP.6.0")
With MyRequest
    .Open "GET", <URL>
    .send ""
    MyResponse = MyRequest.responseText
End With

Solution 2:^[2]

XMLHTTPClient.Open "POST", WebServiceURL, False

change above to true and make it synchronous (waits for response back before continuing)
