Anyconnect DUO SAML

I can get my user to authenticate via DUO SAML integrated with Anyconnect one time. The next time the user authenticates the Cisco Anyconnect Login presents the user with Can’t reach this page. What is interesting is the url displayed is not the full login url that I setup within the Anyconnect profile.

Has anyone see this? It works perfect the first time the user authenticates but once they disconnect they are unable to reach the DUO login page for some reason.
