I hosted my Minecraft server the other day, and I logged on only to get this error message: Failed to verify username! [internal error java.net.ConnectException: connect: Address is invalid on local machine, or port is not valid on remote machine]

I recently got a new computer that runs Windows 8, so I'm not sure if that's the problem, but I am able to log on to other servers.

Notes:
My Minecraft and server are both 1.4.6
My computer runs Windows 8
The server is a regular Vanilla Server that I host
I have no mods installed

Can someone please help? I need this server working before December 26th at the very latest.

Can anyone help?

I'm having the same exact problem. Can you tell me how to put the server into offline mode? Or direct me to where I can find out?

Never mind I figured out how to put the server into offline mode.

Just a tip but i recently had the same problem when running my home testing server, and if you have windows 8 did it come with kaspersky? Because for some reason kaspersky does not like running a server.... so you have to disable it for a bit to get on your server....

Turn it to LAN under options, that's offline mode.

I'm having the same problem. It works when i put it into offline mode but then hackers will be able to get in with any username. Is there a way for it to authenticate my username in online mode or is that out of the question?
