Laravel mailable. Why my queued messages are not sent?

Question

• I have two mailable clasess: Notification and UserRegister

• On develop environment both work fine

• On production environment only Notification works properly.

• In this case, UserRegister works if it's sent directly but not when queued. It tries till 255 attempts are reached and then it stops.

    Mail::to($address)->send(new UserRegister($user)); // works fine
    Mail::to($address)->queue(new UserRegister($user)); //it doesn*t work. Always on queue
    Mail::to($address)->later($when,new UserRegister($user)); //it doesn*t work. Always on queue
  

• I have cleared all caches in production. I have executed "composer dump-autoload".

• My .env parameter for queue is database on both environments:

QUEUE_DRIVER=database

• I have restarted the production server
• There could be something wrong on my supervisor configuration?
• No idea what else I should do

Thanks for any help

Please verify the below task and try again

• The problem happens if the queue worker not running on the production server.
• The 'config/queue.php' is not set up properly.
• The 'queue' table is not found.
• When emails are not saved in the correct table.
• You have too many emails so the queue needs more time but timeouts are too quick. So need to increase the time.
• If you are using Supervisor to manage the queue worker, but you do not update the configuration file (/etc/supervisor/conf.d/yourapp.conf) correctly and when directory paths are not correct for the production environment.

If you need more information about the queue then please go to "https://laravel.com/docs/10.x/queues#main-content".

ISSUE AND SOLUTION IS IN SUPERVISOR!!. The problem is solved. I was using queue:work to run my queue. Running the queue with queue:listen solved the issue.
