Can't connect Google account

Question

When I go to Settings -> Synchronisation -> Google

It seems like a windows is going to open but closes immediately.

I don't have any error code or any other message.

Same here... It used to work flawlessly, but now I cannot open the synchronization through Google anymore...

Same problem.  Impossible to synchronize via Google.

(Worked fine in few days before)

Still a problem for me. Been going on for months. The popup saying synchronization has failed is incredibly annoying, especially since there seems to be absolutely no way to fix it.
