When loading the site game.cardhunter.com, I recieve the following information: "Card Hunter is currently down for maintenance. Please try again in a few minutes. Try Again". The reason for this seems to be a Problem with the configuration or the certificate. The script cardhunter_client.js contains a function to check the server status calling https://live-server.cardhunter.com/check_maintenance.jsp, what fails with no other message when called within the script, resulting in the script "thinking" the server has a maintenance timeout. When accessed direktly, you get detailed information. This happened to me at two different computers using the latest version of firefox, that seems to have changed something in the security settings. Maybe it is just a default setting in new installed versions of the program, or... I don't know. I managed to solve this problem for me, but it might become a problem for other user, too.
