I've configured the Meraki SSID with a splash page (walled garden; blocking access till sign-on is completed) using an internal NPS server. The NPS server configured in the SSID successfully and responds when testing it in the Access Control screen. On the Duo side, I have the Radius SSID application in the Duo authconfig file correctly as per Duo support but when testing it, after entering the users un/(email address) & pw on the splash screen, the auth attempt never hits the Duo proxy server. The goal is for the user to get the Duo MFA prompt after the user is authenticated at the Meraki splash screen. All the configurations are correct according to this article but I'm unable to capture the Temporary Redirect HTTP packet after the GET that returns to allow the user access to the internet and connect to the SSID. I've made wireshark captures for both Duo and Meraki support cases with no resolution to this matter from both sides. Any guidance would be appreciated - thank you in advance
