I have a Laravel project v8 and I have created a cron job for database backup

It works every minute, but when I specify the time of day, it doesn't work.

The project time zone is "Asia/Kolkata" and my GoDaddy shared server time zone is UTC.

kernel.php

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        // $schedule->command('backup:clean')->everyMinute();
        $schedule->command('backup:run')->cron('51 3 * * *');
    }

    /**
     * Register the commands for the application.
     *
     * @return void
     */
    protected function commands()
    {
        $this->load(__DIR__.'/Commands');

        require base_path('routes/console.php');
    }
}

My cronjob on Cpanel.
