laravel after change domain dont work links

Laraval project was in development mode on public IP without domain. Everything worked perfectly, but after changing DNS in my domain to public IP, the project laravel works only on the main page and all links https://mainpage.com/links show The requested URL was not found on this server.

all commands used, without help

php artisan cache:clear
php artisan config:clear 
composer dump-autoload
php artisan route:cache

.env changed APP_URL=http://mainpage.com

when i change APP_DEBUG=true dont work

Any suggestion ?
