Looks like you ran the artisan down command, but not the up command. Just run:

php artisan up

and than you will get:

"Application is now live."

Solution 2

if have tried php artisan up command and your site still not up and gives 503 then ,

delete down file inside /storage/framework/

Solution 3

I just have fixed PHP version to the latest then I goes to "Shell option in panel" and entered this command and my app is live now. php artisan up

The cause of the error likely stems from Apache and PHP-FPM becoming overloaded with requests. PHP-FPM, and occasionally Apache, will need adjustments to their limitations to get around this.

To start, we recommend attempting to adjust the PHP-FPM pool limits from within the WHM "MultiPHP Manager." To do so globally:

[1] Access WHM >> MultiPHP Manager
[2] Select "System PHP-FPM Configuration"
[3] Adjust the "Max Children" and "Max Requests" fields. We recommend incrementing in values of 5 to 10 to ensure that PHP-FPM does not get overloaded.
[4] Save your configuration settings

To perform these changes by domain:

[1] Access WHM >> MultiPHP Manager
[2] Scroll down and locate a domain that experiences the problem.
[3] Select "Edit PHP-FPM" for the domain in question.
[4] Adjust the "Max Children" and "Max Requests" fields.
[5] Save your configuration settings

If you have run php artisan down previously then you may face this issue. You have to make this up using php artisan up command

Why this happened? as I did the same mistake php artisan down and then run

 php artisan serve

and CLI was showing me

<http://127.0.0.1:8000>
[Thu Dec 31 00:25:23 2020] PHP 7.4.3 Development Server (http://127.0.0.1:8000) started

application started but it was showing 503 service Unavailable then run php artisan up and application started.

run this command to make this workable

php artisan up
