Laravel Queue Restarts After 60 seconds

I have a job like this:

//Run very intensive script that generates files
//Notify the user that the job is done

I know that the script takes 4-5 minutes to run since it is the time needed to generate all the files. However, after exactly 60 seconds, the job is removed (i.e. I do not see it in my jobs database table) and the user get notified. Then, every 60 seconds, until the script is done, the user is notified that the job is done.

The job do not fail. The job is only present in the jobs table for the first 60 seconds. The file-generating script runs only once.

I use supervisor:

[program:queue]
process_name=%(program_name)s_%(process_num)02d
command=php artisan queue:work --timeout=600 --queue=high,low
user=forge
numprocs=8
directory=/home/forge/default
stdout_logfile=/home/forge/default/storage/logs/supervisor.log
redirect_stderr=true

Here's my database config:

'database' => [
            'driver' => 'database',
            'table' => 'jobs',
            'queue' => 'low',
            'expire' => 600,
        ],

The behaviour is the same if I use redis

'redis' => [
            'driver' => 'redis',
            'connection' => 'default',
            'queue' => 'low',
            'expire' => 600,
        ],
