Ubuntu 14.04, apache2 . HTTPS,Domain,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?

Thank You for all your help in advance
