replace default cert on securelogin with a new one, with multiple common names does not work

we were replacing the securelogin.arubanetworks.com url that is used for captive portal redirect between clearpass and aruba controller.

We used the already installed certificate on the controller that has 4 common names/alternatives in it.

When doing the redirect from clearpass we get a host cannot be found DNS error. This means the controller is not picking up the dns query for some reason, We suspect that its because of the 4 common names that we have in the certificate. Did someone already try to put a cert with alternative names on the arube captive?

Subject alternative names will not be available for use during captive portal authentication. You'll need either a wildcard or standard certificate. Please see here: https://community.arubanetworks.com/t5/Controller-Based-WLANs/ArubaOS-Default-Certificate-Revocation-FAQ-Controllers/ta-p/275809
