Laravel url parameter returning 404 once hosted

I'm developing a Laravel website. Everything is working fine on localhost. But once hosted online with 1&1, when I add a parameter in the route, it's returning an error 404 (not found).

In 1&1 the root url is redirecting to the file "public" of my laravel project.

And the .htaccess in this public file looks like that :

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

Does someone know what could be the problem ?
