Turns out I forgot to set the Elliptic Curve to secp384r1, which is needed to be fully compliant with WAP3 192 bit mode.
My 24H2 devices can authenticate after that change.

Thank you, from the logs it seems like 24H2 refuses to use TLS 1.2 during handshake process and maybe openssl or Freeradius doesn't support TLS 1.3 ciphers?

Below is the error for my W11 24H2 device

Same device  after I changed tls_max_version = "1.3"

Is there any other settings I could change for Freeradius to try get this to work?

Hello,

I'm wondering where I can get more debug output from the Freeradius plugin, at the moment I am only getting the following output with when trying to authenticate with EAP-TLS.

eap_tls: ERROR: (TLS) TLS - Server : Error in error
Login incorrect (eap_tls: (TLS) TLS - Alert write:fatal:handshake failure): [radiusdebug/<via Auth-Type = eap>] (from client u6mesh port 3)

This error only comes up with Windows 11 24H2 clients connecting to WPA3 192bit WiFi. I didn't have this problem with 23H2 or prior & no other operating systems have this issue.
