Hi Ryan,
Yes, problem seems with the hostname and/or IP address you are using.
These type of problem generally means... either `ws14008352u.pclan.citec.com.au` is kind of _complex_ hostname for Gluu Server to generate internal certificate OR the ip address you are using is not associated with actual VM's IP.
Can you please _record_ the _whole_ screencast from your installation process and share with us?
