Sounds like the supplicant trying to use only ciphers that were not
allowed at this point. I would need to see more context in the debug
log (i.e., including the previous EAP messages that started EAP-FAST)
and ideally, also a packet capture log showing that exact ClientHello
message to see what exactly the supplicant was trying to do.

OK, so this is for anonymous provisioning.. Could you please also send
debug log from wpa_supplicant showing what it is doing when this failure

Depends a bit on how you handle provisioning. Anonymous provisioning
(like the configuration above) is not that secure, so verifying server
certificate during the provisioning step would be advised if you cannot
guarantee a safe location to do the initial setup. Once the PAC has been
provisioned, there is less need for certificate validation.
