Description of problem:

Reload the network service is producing "Job for network.service canceled." and leaves the service in inactive state.

# systemctl status network
● network.service - LSB: Bring up/down networking

I am not quite sure what is the exact purpose of the reload feature for the networking service, but since is present, i would expect it to work. Checking the code, it seems to me like it should produce the exact result as "systemctl restart network" 

less /etc/rc.d/init.d/network

...

restart|reload|force-reload)    <---
    cd "$CWD"
    $0 stop
    $0 start
    rc=$?
    ;;
*)
    echo $"Usage: $0 {start|stop|status|restart|reload|force-reload}"
    exit 2
esac

exit $rc

Same result when you try to reload by the script itself 

# /etc/rc.d/init.d/network reload
Reloading network configuration (via systemctl):  Job for network.service invalid.
                                                           [FAILED]
