error when starting up radius using systemctl start radiusd.service command

[null) (null]

When I startup using radiusd -X, it doesn't give me the error and radius server start successfully attached is the debug log details.

But if I startup using the "systemctl start radiusd.service”, it failed to start and radius.log appear the following message

# systemctl start radiusd.service
Job for radiusd.service failed because the control process exited with error code. See "systemctl status radiusd.service" and "journalctl -xe" for details.
