I'm sorry for that. It was unexpected for us and came from hosting provider side. I should have posted "We have issues, but I don't know when they are fixed", but was afraid to post like that. Though now I realize it was better to let you know still.
Thank you for the report. Is the game entirely unplayable? If you press the ok, does the dialog come back immediately? One thing that you can try is to refresh the game by pressing F5.
Sometimes if client version outdated, incognito mode of the browser helps to start the game.
