The package does not have a lot of input validation in the webGUI. If NUT will not start after configuration, check the System log from the pfSense® webGUI from Status > System Logs) for log entries starting with nut:. The culprit is likely explained there, such as selecting a cable for a driver type that does not need (nor permit) the cable selection.

If the system log doesn’t offer adequate information, such as simply logging:

nut: Service failed to start: check configuration

Log in via SSH and choose option 8, then run the following command:

/usr/local/etc/rc.d/ start

Configuration errors will be displayed in the output if any are found.
