I don't know anything about the UPSXML module, but what you posted does tell me that you are connecting to the server ok, and even retrieving information from it, so you don't have any problems with connectivity (IOW, your cURL is just fine.
The line I just quoted seems to be a good clue where to look though. Does this module have a selection of different "pickup types" for you to choose from? If so, select a different option.
If not, I can't be of any other help.
