well, i recently got mine

craft, and i planned to play with some friend, (or even in more server), and i just found out two problems i got, 1 when i try to go to a server/friend's server, saying this. "failed to log in: The authentication servers are currently not reachable. Please try again", and the other problem is that my skin won't load, i tried a lot of stuff like unistalling minecraft and downloading it again,, changing "disk", updating java, but nothing happened, please respond soon as possible.
