Freeradius giving certificate error

[Dhanushka Parakrama]

Hi All .

We are running freeradius 2.1.10 with  WPA Enterprise authentication with
EAP-TTLS  and setup is working is fine

Then we have regenerated the new certificates via .*/bootstrap *command

Then we tried to login to WIFI .  but our freeradius stared to throw the
below error





Wed Mar 29 20:26:02 2023 : Error: TLS Alert read:fatal:bad certificate
Wed Mar 29 20:26:02 2023 : Error:     TLS_accept: failed in SSLv3 read

Is there any reason for the above error ? How can I fix it ? , Please
advice


Thank You
