[[cat-users]] "Can't connect to this network" in Windows 10

Hi all,

I have a new Windows 10 machine that will connect to eduroam just fine
if I verify our cert's fingerprint manually, instead of using CAT.
When I install CAT, the network configuration is added, but as soon as
I click Connect, "Can't connect to this network" is displayed under
the SSID name in the menu.

Does anyone have any tips for collecting data about why the failure is
happening? Since I am also one of our realm administrators, I was able
to look on our RADIUS server logs. The client is sending what it calls
a "TLS alert message" and thus the connection is rejected.

I know I have loaded our root and intermediates correctly because the
CAT works fine on other OSes (iOS and Linux are the ones I have access
to, and have tried).

Is there any place in Windows I can find more information about why
it's failing, or is there anywhere else I can check? Any pointers
would be appreciated.
