Can't log in to xbox live

I tried to switch to beta. I started the game. And it immediatly crashed. I switched back to normal. And then i couldn't sign up. I tried with 10 different accounts and doesn't work. Everytime it sais: "something went wrong. Try again or try in xbox.com" i tried there. Nothing changed.

I switched back to beta and i logged in but it said that my account had an error, i tried to play with my friend but his world wouldn't show up in the friends section. I tried to uninstall and reinstall(beta version) and it said:"something went wrong. Try again or try in xbox.com"

The account works i can play with my friend from my xbox but when i try to play from my phone it doesn't let me log in and i tried to play using different accounts but ended up having the same result.
