apache redrict 301 from https://www.domain.com to https://domain.com - apache

Question

im trying for hours to redrict https:// www. domain .com to https:// domain .com with 301.
I have a certificate for domain .com but no wildcard for www. domain .com.
I tried the following:
RewriteEngine On
RewriteCond %{HTTPS} =on
RewriteCond %{HTTP_HOST} ^www\.meinedomain\.de$ [NC]
RewriteRule ^(.*) https://meinedomain.de/$1 [L,R=301]
and
RewriteEngine On
RewriteCond %{HTTPS} on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
and
Redirect 301 / https://mineyourmind.de/
None of this works. Any ideas what could be wrong? I have added this directly to the apache settings and it is working great for http:// www. domain .com and http:// domain .com to https:// domain .com but not for https:// www. domain .com.
At the moment I use the following config. Every redrict works fine, instead of the https://www.mineyourmind.de to https://mineyourmind.de
How should such a file look like ?
<VirtualHost *:80>
ServerName mineyourmind.de
ServerAlias www.mineyourmind.de
Redirect 301 / https://mineyourmind.de/
</VirtualHost>
<VirtualHost *:443>

Second Edit:
<VirtualHost *:80>

ServerAlias www.mineyourmind.de
RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\.mineyourmind\.de$ [NC]

Answer 1

If you request https://www.meinedomain.de/ and your cert isn't authorized for www.meinedomain.de, then you'll get a security warning regardless of how you redirect. The redirect can only happen after they accept the security exception.
Make sure you've put those rules in the SSL vhost's config, not the non-SSL one. Apache usually has them separate. If that still doesn't work, you can try just putting this in an htaccess file in your document root:
RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\.meinedomain\.de$ [NC]
RewriteRule (.*) https://meinedomain.de%{REQUEST_URI} [R=301,L]
