Citrix connect error on Controller (when running on a remote Load Generator)

Hello,

I am trying to run a Citrix script on the Controller, I noticed the script runs fine when it is LOCAL HOST however when I use a remote load generator, the script fails immediately. Note that the Agent on the Load Generator is installed as a Process (not as a Service) and I'd logged in manually to the Generator machine
 
The error that I get on the controller is below:
 
vuser_init.c(4): Error: Connect can not be established - Last Error=64, Last client error=0
 
Anyone who may have faced this before and any suggestions that you could provide would be appreciated.

Thanks,
