I was using Pulse successfully today. Then around 4:00 PM after timing out due to my laptop going to sleep, I lost my saved VPN connection. I set it up again. Now every time I authenticate, the connection is successful but I receive no IP address. Looking in the advanced configuration, I see "Tunnel type: <tunnel not enabled>" (see screenshot)
Are you sure that the server URL is correct and you aren't missing anything? You may be going to a sign-in policy that doesn't allow full tunnel VPN. Are you able to go to the URL and log in from a browser?
When you log in to the portal, is there a Pulse Secure start option?
This doesn't appear to be a client issue. I'm thinking you may just be getting a role that doesn't allow for client VPN connections, or there is no IP address Pool. Can you check with IT? If you have access to the admin console (and are IT), you'll need to check logs, etc.
