TLS error

Hi In other threat I commented about problems connecting and I discovered now this error TLS Alert read:fatal:unknown CA TLS_accept: failed in SSLv3 read client certificate A rlm_eap: SSL error error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca SSL: SSL_read failed inside of TLS (-1), TLS session fails. TLS receive handshake failed during operation Im changing COMODO certificate, but I don't know where checks to find this CA. Suggestions?
