CodeIgniter 3 routes don't work in HTTPS

In my work we are migrating some websites to HTTPS, but the routes have stopped working under HTTPS and the server returns error 404, they are just putting the /index.php/ and under HTTP they have been working correctly.
I've been searching but nothing I've found works

This is my config.php:

Code:

$config['base_url'] = 'https://myweb.es';
$config['index_page'] = '';
$config['uri_protocol']    = 'REQUEST_URI';

And this the .htaccess:

Code:

Options FollowSymLinks
<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule>

Thank you in advance
