There is a known issue with all API calls currently. This will impact an increasing number of players and servers over the next few hours due to the SSL certificate expiring. This will impact all attempts to authenticate, join servers, and so on. Additionally, you will start seeing SSL certificate warnings/errors on the forums and other KAG sites using SSL. We should have this resolved within the next few hours and will keep you posted.
