Your server certificate is issued by an intermediate CA, which in turn
ends in a root CA.

For Android, it is only possible to load root CAs onto the device, not
intermediates.

The intermediate is however /required/ for certificate validation to work.

The only way to make this happen is by making sure the RADIUS server
sends that intermediate certificate during the EAP exchange. If it is
*only* sending the server certificate, the behaviour you describe occurs.

If that's the issue, then you should have a corresponding warning in the
admin area of CAT when running the realm reachability tests. Is that so?

Greetings,

Stefan Winter
