Adding HTTPS in WP general (second site) - redirecting on another domain?

Hello,

i run apache on Ubuntu. Installed 2 wordpress websites and installed ssl cert on both. All was working fine. I have site1 and site2, site1 i changed in wp general URL to HTTPS. And its working with https.

But have problem with site2, when I add HTTPS for that domain, i got redirect to site1.

And only able to change URL from database from site2.

Also now when i put https://site2.com in address bar its showing me content from site1 but domain is https://site2.com

I hope you guys understand me what i want to ask.

Site2 config in /etc/apache2/sites-available/site2

<VirtualHost *:443>

    ServerName site2.com
    ServerAlias www.site2.com

    DocumentRoot /var/www/site2.com
    SSLEngine on
    SSLProtocol all -SSLv2
    SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM

    SSLCertificateFile /var/www/site2ssl/site2.com.crt
    SSLCertificateKeyFile /var/www/site2ssl/site2.key
    SSLCertificateChainFile /var/www/site2ssl/site2.crt


</VirtualHost>

Same is for site1 just other paths and site1.

Thanks
