Dynamic VPN help

I have looked through several tutorials and made many attempts, now sure where I am missing the boat.

Following is my most recent attempt, no dice. (I have removed non-relevant information)

With each attempt I am received the same error.
"Error 1110: Unable to communicate with the server."

Pulse secure on Windows 7 system.
