Confirmed. I can't join my wife's LAN game either, Minecraft gives me an error message about an invalid login token but restarting the game does not help.

Did your Launcher say Play Offline when you started the game?

I think Mojang's servers are having problems as I logged out to log back in thinking it would help, but now I get "SocketTimeoutException: connect timed out" and I can't play anymore.

Appears to work fine in 14w33c. I was able to whitelist kumasasa and jeb_ in-game and via Multicraft.

I am trying to whitelist my step-son on our family's private server, currently running 14w32d.

When I try in-game via the /whitelist add command, I get this:

An unknown error occurred while attempting to perform this command.

When I try via the Multicraft control panel, I get this:
