Hello, i used option AllowUntrusted TRUE with the ssl output module but i have still error ssl verification failed

ERROR SSL certificate verification failed: unable to get local issuer certificate

this option is not supposed to avoid this error ?

https://docs.nxlog.co/ce/current/index.html#om_ssl

My output conf:

<Output ssl>    

Module  om_ssl    

Host    mysyslogserverPort 514

AllowUntrusted TRUE

OutputType  Syslog_TLS

Exec        to_syslog_ietf();CAFile      

</Output>

regards

Guillaume
