Failed with result 'exit-code'

[killreal]

Hello!

I has installed Snort and Barnyard2 on  my Ubuntu 20.04.1. They work normally, but when I try to make Barnyard2  as service, I will get error "barnyard2.service: Main process exited, code=exited, status=1/FAILURE". I will get this error, when i reboot my system. But if I executing the command "sudo systemctl start barnyard2" and check status service, I will have "active (running) service". 

My barnyard2.service file:
