Web Client Access from other workstation

Web Client Access from other workstation

I have just install ServiceDesk Plus MSP standard trial onto a fresh install of Windows Server 2012 R2.  I can access the web client on the server just fine and it is work great from there. However if I try to access it via the URL from another device it isn't working.  Can someone please help me with this issue.  I want to trial this software but apparently Zoho will not support their product if you haven't purchases it.
