Hello,

Sure.

The CA data is curated by the organisation's eduroam administrators.

The data I found lists *two* CAs, one of which is the one you attached.

The other one is also a root CA, but it seems to be an old, discontinued
one. Subject: C = SE, O = AddTrust AB, OU = AddTrust External TTP
Network, CN = AddTrust External CA Root

On most Android versions, it is only possible to define *one* root CA as
trust anchor.

With the choice of two, apparently the wrong one is installed as a trust
anchor in this case.

If you are the admin and have access to the CAT administrator interface,
the trivial fix is to log into the admin interface and delete the old CA.

Greetings,

Stefan Winter
