The hearthbubby is currently down for all CN server Hearthsone players The reason is that one day or two right after the last update of bubby came a strange update for Hearthsone, seemingly exclusice to CN server. No changelogs are there to explain if any differences are made except for the version number, but we did download something. Now we need the bubby updated(again) to handle the situation. Note that CN server also uses a unique Blizzard Game Platform(previously known as Battle.net) which can bu downloaded at http://hs.blizzard.cn/download/ pressing the button marked in the picture.
