my system connection settings configured correctly (Firefox, Thunderbird, PhpStorm etc. works fine). I checked with Wireshark what ORM2 Designer connect for when it starts. It called our DNS for stark.orm-designer.com and recieved 18.104.22.168. Then it starts connecting to 22.214.171.124:80 directly and ignore sytem connection settings.
I'm using openSUSE 12.2. We connect through squid proxy to the internet.
