After going through the forums I found the answer here: https://communities.vmware.com/thread/518369?start=0&tstart=0
Essentially, you need to add the the VCSA IP address and hostname to the hosts file on the computer that you are connecting to the VCSA, such as your laptop or workstation. (/etc/hosts on *NIX or C:\Windows\System32\drivers\etc on Windows). Once that is done, you should be able to export the OVF or OVA file.
Hope this helps you
