php artisan shows no output (blank) on cli in live environment

Hi. I have a problem with Laravel when I put it into the live environment. I have created 2 commands results:generate and get:ftpResults. running php artisan get:ftpResults runs fine and executes php code in the function handle(), but when I execute php artisan results:generate the function just returns a new line as blank, no output.

im using Laravel 5.6.29 in cPanel environment Centos v7 with Lightspeed.
