SSL VPN RDP Bookmark Does Nothing

[simple1689]

I've got some Chromebook users that need to use SSL VPN. I figure to have them login to the Web SSL Portal and use Bookmarks to RDP into Terminal Server or their Workstation. 

When I setup a RDP Connection Test to Terminal Server, just a white screen comes up. Nothing else happens. This is with Chrome and IE 32-bit. 

RDP Connection Test Settings:

Type: RDP 

Host: IP of Terminal Server and tried FQDN as well

Screen Width and Height: Left at default 

Username: domain\username & Username (samAccountName)

Password: correct password used

Full Screen: Checked or Unchecked

Only a white screen will come up. Nothing else happens. Trying to figure if there any requirements like Java, ActiveX, etc.

What FortiOS version are you running?

5.2 used Java for it's SSL VPN portal. This was updated to HTML5 in 5.4. I definitely recommend going to 5.4 for the SSL VPN portal as it's so much cleaner.
