It looks like the Microsoft login page is redirected as part of your captive portal. You should exclude the Entra ID authentication services from redirection. Check here for which domains to exclude.

Can anyone share their experience with IAP and Microsoft Entra ID verification? When I configure IAP, the Microsoft login page pops up and it says that the certificate does not match and I cannot continue. The AP I manage with MM does not have this verification problem.
