ErrUchIsDown in poker-dice

I would like to give some feedback about ...

From: http://www.checkio.org/mission/poker-dice/solve/

HTTP_USER_AGENT:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/600.7.12 (KHTML, like Gecko) Version/7.1.7 Safari/537.85.16

I tried to google for `ErrUchIsDown` with no luck, it seems that this problem appears from time to time here in CheckiO but I have no clue whether it's a platform problem or a program problem.

Would you take a look?

Thanks, Flavio.
