Hi, What does this message mean? (2) eap: Calling submodule eap_peap to process data (2) eap_peap: Continuing EAP-TLS (2) eap_peap: Peer indicated complete TLS record size will be 88 bytes (2) eap_peap: Got complete TLS record (88 bytes) (2) eap_peap: [eaptls verify] = length included (2) eap_peap: (other): before SSL initialization (2) eap_peap: TLS_accept: before SSL initialization (2) eap_peap: TLS_accept: before SSL initialization (2) eap_peap: <<< recv TLS 1.3 [length 0053] (2) eap_peap: >>> send TLS 1.0 Alert [length 0002], fatal protocol_version (2) eap_peap: ERROR: TLS Alert write:fatal:protocol version tls: TLS_accept: Error in error (2) eap_peap: ERROR: Failed in __FUNCTION__ (SSL_read): error:14209102:SSL routines:tls_early_post_process_client_hello:unsupported protocol (2) eap_peap: ERROR: System call (I/O) error (-1) (2) eap_peap: ERROR: TLS receive handshake failed during operation (2) eap_peap: ERROR: [eaptls process] = fail (2) eap: ERROR: Failed continuing EAP PEAP (25) session. EAP sub-module failed (2) eap: Sending EAP Failure (code 4) ID 216 length 4 (2) eap: Failed in EAP select (2) [eap] = invalid I'm getting this only when Windows 7 and other older clients try to connect, but not with Windows 10 clients. My version of openssl is 1.1.1g and frreradius is 3.0.20. If it's a TLS version issue, is there a way to explicitly enable whichever version now seems to be unsupported (TLS 1.0?). Regards, Vieri
