I got an answer on my ticket:

Hello,

Thank you for contacting us regarding ArcheAge.

We apologize for the inconvenience this issue has caused, and we can understand how frustrating it would be to be unable to participate on the public test server (PTS). At this time we do not offer support for the PTS and the server will very often be offline or inaccessible. To check availability of the server or report issues, please check out the PTS forums:

ArcheAge - http://forums.archeagegame.com/forum...ic-Test-Server

Please keep in mind that the costumer support is unable to assist on PTS. Good luck and thank you very much for participating on our public test server.

If you have any additional questions or concerns, please don't hesitate to let us know. Thank you for your continued support and for playing ArcheAge.

Sincerely,
Yuuki
Don't know what to do....
