Internal error during EAP-FAST

[Sebastian]

Well, it's not a desktop or laptop, it's the Cisco access point itself
(the AP tries to authenticate on the switch port) and I don't have a
lot of options to set there – basically just what kind of EAP I want
and that's it.
(EAP-PEAP aborts after it receives a NAK  and EAP-TLS never receives a
reply to it's Access-Challenge - that's why I hoped that at least
EAP-FAST would work …)

But thank you for your help – I will double-check if I can change the
requested TLS version somehow.

Best regards
Sebastian
