Cannot POST to create schedule - (500) internal server error

Question

I am trying to create a schedule using Raylight and Restful Web services using a post to
http://xxxxxxxxxxx:6405/biprws/raylight/v1/documents/6385/schedules 
when I do I get an error
'The remote server returned an error: (500) Internal Server Error.'
I suspect its to do with ports being open and closed as our system has all ports locked down by default and we have to get them opened as we find the need.
Has anyone any idea as to where or how I might be able to find details of ports that need to be opened or services that need to run with specific ports rather than automatic ?
Any help much appreciated as this is fast becoming a major stumbling block - we keep fixing one thing only to find another, unfortunately we are newbies to the SDK as well as newbies to 4.1

The request is being made to the following Uri where 10781 is the document CUID that is having the schedule added :-
"http://bc0boapp01.uat-tpplc.local:6405/biprws/raylight/v1/documents/10781/schedules"
The body that is being POSTed is :-
<schedule> 
      <name>ONCE Test</name> 
      <destination> 
              <filesystem /> 
   </destination>
      <format type="webi" /> 
      <once retriesAllowed="1" retryIntervalInSeconds="120"> 
           <startdate>26/03/2015 12:00:40</startdate> 
           <enddate>27/03/2015 12:00:40</enddate> 
    </once> 
</schedule>
