I have been having a weird issue lately where I can't access my localhost development server with Chrome unless I have an internet connection, which doesn't make any sense because I shouldn't need a net connection to access my own machine, and I can get to it just fine in Firefox.  A little googling lead me to this Chrome bug that has an easy enough fix at the very bottom.  All you have to do is launch Chrome with this additional argument: "--enable-ipv6".
