Redirection and https not connecting without the WWW

I have had a few issues with my redirects. (i have left off the end of the URL as i cannot post more than 2 links)
i have managed to now get all variations of http and blank and https to point to https :// www . Mysite
without and off www .www . issues

however it wont fix when i leave the www. subdomain off with https ( https :/ / mysite )

Currently i have these redirections set up on my dashboard:
> www . Mysite to a server (IPv4 - A) xx.xxx.xxx.xxx
> Mysite Permanent visible redirection https : // www . Mysite

htaccess is as follows
>
> RewriteEngine On
> RewriteCond %{HTTPS} !=on
> RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]
> RewriteRule ^index\.php$ - [L]
> RewriteCond %{REQUEST_FILENAME} !-f
> RewriteCond %{REQUEST_FILENAME} !-d
> RewriteRule . /index.php [L]
> Redirect gone /404.php

Can someone help were i have gone wrong as i have got into a right mess trying to fix this. and cant get my head around why changing either causes loops or issues such as double WWW . (https // www . www .mysite)

cheers
