404 routes problem laravel

Hey guys I'm trying to deploy my app in production but I'm facing 404 not found error on laravel routes..

I followed some tutorials and did the following

sudo a2enmod rewrite
sudo service apache2 restart

edited /etc/apache2/sites-available/my-file.conf

    DocumentRoot /var/www/html/
        <Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
        </Directory>

edited /etc/apache2/sites-available/apache2.conf

from

    DocumentRoot /var/www/html/
        <Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
        </Directory>

to

    DocumentRoot /var/www/html/
        <Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
        </Directory>

it get fixed but when I access again for a couple of times i get back the same error.. couldn't know why this happening..
