problem with htacces and https

Hello
I've made simple htacess from manual:

Code:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

If I coming via http - it works
If I coming via https - it works, but changes the address in address line from https://example.com/zzz/ to https://example.com/index.php/zzz/ 

Code:

$config['index_page'] = '';
$config['uri_protocol'] = 'REQUEST_URI';

What can I do to remove this "index.php" from https links?
