So good news.
And tx 4 not giving up, like I had.
So after unchecking "[ ] Hide Standard Output" checkbox, it triggered and worked.
Then I re checked it and it worked.
And I paid close attention to "next run" info.
Im gonna guess the timezone was probably what made it work. Maybe the server just needed more time to sync idk
In any case, I have successfully scheduled a poweroff at night
Didnt use absolute path, and still havent looked into NTP servers.
Looks like my freenas adventure continues.
Next adventure will be setup syncthing and maybe clamav.
Tx again, really appreciate it, if it wasnt for you, I would of given up.
Big hugs from me.
Take care, stay safe in this time.
Regards
