Hi Keith,
My end-user also having the same problem on the hotspot after upgrading the firmware from ver 9.6 to 9.7. All the while, they using ver. 9.6.0.0.267 without any issue. The hotspot are set redirection to
https://10.24.129.76 for authentication and after user is valid it will redirect back to
https://10.24.129.76/my.policy. Inside the walled garden we set the unauthenticated users to the IP address of login page. When user get connected to WLAN and open the browser the login page will prompt automatically.
For ver. 9.7 it doesn't happen.
