Laravel package:discover show only half packages

After migrate laravel project to domain @php artisan package:discover shows only half of packages

php artisan cache:clear; php artisan config:clear; composer dump-autoload all used

after project migration are there other possible commands or is enough php artisan key:generate and add .env database access ?

I quess not all packages work.
