Status code 400 at System Update A210

Hello,
as the title says it appears on my A210 when I press System Update:

Update Service temporarily unavailable.
Please try again later.
Status Code: 400

how can I fix or that will come at all an update for the A210?

Regards


who one probably just server problems. Just try again later. Will be officially distributed as an update?
If not is possibly deactivated the update service.


I do not think it is a server problem, as it has been for at least 2 weeks. Before that there was the error code 1004
