mod_rewrite in htaccess redirecting to index when trying to force https and www

Greetings,

I'm trying to force rewriting URLs that do not use the HTTPS protocol and do not have the www through mod_rewriter in htacess.

I'm using codeigniter, so I take the index.php.

<IfModule mod_rewrite.c>
    RewriteEngine On

    Options -Indexes
    Options +FollowSymLinks -MultiViews

    DirectoryIndex index.php

    #Forçando HTTPS
    RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} !^virtual.host(.*)$
    RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=302,L]

    #Forçando www
    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=302]

    #Retirando index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?$1 [L]
</IfModule>

The problem is that when I test without https or without the www, in some cases it is redirecting me to the index ( link ), in some cases it works correctly.

I have tried in many ways to get around but to no avail.
