Problem with Facebook Sharing

Hello.
In the logs tab, i revice this problem:

18-01-2015 12:59:11 PM Error for posting on facebook for – Instagram Rapture: Milioane de conturi au fost ?terse, spre disperarea utilizatorilorOperation timed out after 5001 milliseconds with 0 bytes received

Why?
My app is created well, and i do not have problems.

Also i did see, on Facebook the link is not short with bit.ly or other services.
