Ubuntu 14.04, apache2 . How to confi HTTPS and Subdomain

Hello

I have created my ubuntu server, bought ssl certificate, installed it on server.

And after there was few difficulties When i’ve typed in browser my domain Without https it showed me blank page than i have found tutorial about how to redirect http to https and i have added to default-ssl.conf this

<VirtualHost _default_:80>
        RewriteEngine on
        ReWriteCond %{SERVER_PORT} !^443$
        RewriteRule ^/?(.*) https://%{HTTP_HOST}/$1 [NC,R,L]
</VirtualHost>
<VirtualHost _default_:443>
        ServerAdmin admin@domain.com
        ServerName domain.com
        ServerAlias www.domain.com
        DocumentRoot /var/www/domain.com/public_html
        RewriteEngine on
        RewriteCond %{HTTP_HOST} !^(www\.)?(.+)
        RewriteRule ^ https://%2%{REQUEST_URI} [R=301,L]

And now everything works perfect, except one, i have few subdomains api.domain.com and support.domain.com , when i type them they automatically redirect to https(but they should be http) and showing me mine main page of domain.com

How to do it right?

Domain that is was talking about is https://smmhouse.com Subdomain http://api.smmhouse.com http://support.smmhouse.com

Thank You for all your help in advance
