getting Illuminate\Queue\MaxAttemptsExceededException in laravel jobs

I have one job which will take 1 hour to run, I already created job-based on laravel documentation, here is my job file.

<?php


namespace App\Modules\Csv\Jobs;

use App\Jobs\Job;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Storage;
use Illuminate\Support\Str;
use League\Csv\Reader;
use Phone;

/**
 * A single excel import job, which can be pushed on to a queue
 */
class UploadCsvDataInTable extends Job implements ShouldQueue
{
    use InteractsWithQueue, SerializesModels, Dispatchable,Queueable;

    public $timeout = 172800;
    /**
     * The excel to import
     *
     * @var App\BulkUpload
     */
    protected $csvUpload;

    /**
     * Create a new job instance.
     *
     * @param App\FeedImport
     *
     * @return void
     */
    public function __construct(CsvUpload $csvUpload)
    {
        $this->csvUpload = $csvUpload;
    }

    public function handle()
    {

        app(CsvUploadService::class)->uploadCsv($this->csvUpload);

    }
}

here is Laravel document to specify a timeout for jobs.

here is code for how I am calling that job.

UploadCsvDataInTable::dispatch($csvUpload)->onConnection('redis')->onQueue('low');

Can anyone help me why my job is getting MaxAttemptsExceededException ?
