Thanks. I've found another server and i'm in the process of getting access (security people take forever). The error is being generated from the sending application.
The strange thing is there is no "link" tag in the XML I'm sending. The XML is also valid. I tried another method to send the data within the app (Workday) and I got no error and it said the file was delivered. However it did not show on the server.
After a successful test (I'm pretty sure it will be) on the other HTTPS server I'm going to see if I can get the erroring server people to monitor their logs while I send the file. Hopefully they can see something as well. I tried looking at Workday's logs but this "link" error is really all that showed.
