Codeigniter remove index.php on https - .htaccess

Question

I am using godaddy as my server provider and I bought an SSL certificate. It gave me some headache with index.php in my CodeIgniter project. I can not remove the index.php from my url.
I researched around and tried everything I found but nothing works for me, so do not consider it as a double please.
If: https://example.com/index.php/home - works perfectly fine
If: https://example.com/home
I get a 404 Error. Not Found The requested document was not found on this server.
So far, I have stoped at these conditions in my htaccess file:
RewriteEngine on
RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} (sale|success|cancel) [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !(static|sale|success|cancel) [NC]
RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteCond $1 !^(index\.php|resources|robots\.txt|static) [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
Any advice would be helpful. Thank you!

remove index.php from $config['base_url'].
Then Use this link to remove index.php from url

then restart server

Answer 2

My Final Result:
in Helpers:
//Force SSL injection
if(!function_exists('force_ssl'))
{
function force_ssl() {
if (!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] != "on") {
$url = "https://". $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
redirect($url);
exit;
}
}
}
In Controllers call the method: force_ssl();
In .htaccess, where the index.php is:
DirectoryIndex index.php
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|robots\.txt)
RewriteRule ^(.*)$ index.php?/$1 [L]
