Redirect from https://mydomain.com to https://www.mydomain.com ?

Hi,

So I'm using ISPconfig v3.1 and I'm having hard time to get redirect from https://mydomain.com to https://www.mydomain.com
Obviously redirect from mydomain.com to https://www.mydomain.com works. I have turned on Sites > mydomain.com > Redirect > Rewrite HTTP to HTTPS and also triied to enter this:

Code:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

under Sites > mydomain.com > Options> Apache Directives but it did not make any difference.
My question is do I have to have both above options and what else do I miss?
Do I need change Sites > mydomain.com > Redirect> Redirect Type ?
My goal is to redirect everything to https for Google SEO

 

Thanks for taking time to reply!
Ok, so are both Rewrite HTTP to HTTPS and what I have in Apache Directives needed?
My goal is when https://mydomain.com is typed to be redirected to https://www.mydomain.com at this point no redirect is happening.
