luceos Ye, not quite sure what information to give as I'm clueless what could be causing it as my other domain works perfectly fine with subdomains and they're both setup with VestaCP with the same options.
Not sure where to start looking on this one ?
Edit: Changed the htaccess of the domain.com to following, now it does not show wrong page any longer, it just removed the "https" instead. Step in the right direction at least, I guess.
RewriteCond %{HTTPS} =on
RewriteCond %{HTTP_HOST} !^domain.net
RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [NC,R=301,L]
