BO4 - Dashboards - not able to add query

Hi,

Getting message below when add component to dashboard ad try and add query.

Have never used dashboards before and have a few .unx universes.

Using bo4 sp08.

Clik here to view.

Have read the note checked out the url and added it as an alias to the server.xml on the actual server but still same error.

I've changed the port number under which the web services run from  6405 to the one Tomcat uses but not sure if this is best practice and now runs.

No firewall issues as same domain so not sure why doesn't work on 6405

Any thoughts.

Thanks
