X11 connection failed

I am trying to setup our firepass unit to deploy a linux desktop through the application access.

 

 

It seems to work at first but repeated logins result in a white screen instead of the linux desktop.

 

 

There is only one error that I can see which reads "Splash: X11 connetion failed: No such file or directory"

 

 

I think I have everything configured correctly but I could be wrong...
