Deploying laravel app to shared hosting - serialized closure error

Question

I'm trying to deploy my laravel app to a cPanel Shared Hosting. Here is the app and system features:

Laravel: 8
PHP: 8.1

I've done these steps:

Changed .env file as like that:

    APP_URL=http://example.com/
    APP_LOG_FILE=/home/example/example/storage/logs/laravel.log
        
    DB_DATABASE=dbname
    DB_USERNAME=user
    DB_PASSWORD='pass'

I pointed out my url to /home/example/example/public folder.
I've cleared all caches and regenerated app key on my local. And I uploaded the files.
Removed storage folder in the public folder.
Followed the steps suggested here.

When try to access, it throws this error:

I can't understand what's the problem.

Thanks.

Showing us the index.php is not very helpful, because it's the same for every Laravel instance. What's inside ".unknown0"? Looks like unserialize is called in there. — Fabian Wagner - a6a2f5842, Oct 07 '22 at 09:53
Sorry, I haven't added the error message to show you the index.php. Also I haven't called unserialize. — sundowatch, Oct 07 '22 at 10:01
Adding a screenshot of what happens in ".unknown0" would really help to get a better understanding for what causes the problem. — Fabian Wagner - a6a2f5842, Oct 07 '22 at 10:07
@justsomexanda-a6a2f5842 sorry, I misunderstood. It redirects me to `vendor/laravel/serializable-closure/src/Serializers/Signed.php` and highlights the `throw new InvalidSignatureException();` line. — sundowatch, Oct 07 '22 at 10:42

@AngelMiladinov yes. I'm running these command before I deploy. — sundowatch, Oct 08 '22 at 03:27

This issue might occur due to change in APP_KEY value in your .env file.

APP_KEY is used for secure data transmission and Laravel recommends to do that by setting it to a random string.

You can run this command:

php artisan key:generate
php artisan config:cache
php artisan route:cache
php artisan view:cache
