hi,

eduroamCAT only supports particular (ie recent) versions of Android.
So long as the devices not working match that requirement, then the
common cause
of problem is that your Android devices dont have the require
intermediate certs installed - the eduroamCAT tool will installs the
root cert (if its not present)
but your RADIUS server SHOULD be sending the entire chain (local cert,
intermediates) and not just the local cert.  (in fact, there are some
random devices out
there that like the root cert to be sent out too but they are slowly
disappearing as people get rid of pretty old kit).

your root appears to be SHA1 - its 2017 - any new deployments should
really be starting with SHA256  (and those with older SHA1 roots,
think about upgrading :) )
