I can't login Xbox live

When I try to log in,
minecraft(or Xbox live) says "Sorry, something went wrong. Give it another try, or try on Xbox.com."
I tried five times with this, but failed to log in been.
Soooo....I can't play minecraft with achievement;(
(Umm...Maybe it was xbox account the problem?)

Thank you for read my discription
