Syslog will not start despite following instructions

[huntson]

I have double-checked the instructions here: https://docs.librenms.org/Extensions/Syslog/#syslog-ng and it appears that I have done everything correctly. When attempting to bring syslog-ng up I get the following:

Job for syslog-ng.service failed because the control process exited with error code.
See "systemctl status syslog-ng.service" and "journalctl -xeu syslog-ng.service" for details.

Output of systemctl status syslog-ng.service

librenms@librenms:~$ systemctl status syslog-ng.service

I have found some more information by running sudo syslog-ng -Fdev
