Authentication to Minecraft.net Failed

Hi,
I am currently having a problem with My server linked with Lilypad. When players try to connect it gives them the error above. These may be things you may need:
My Config:

The error on Console:
http://pastebin.com/DcdE71RR
I am also running the latest version of lilyPad. If you want to try and connect to the server use this IP: play.syncmc.com (Not Advertising). Anyways thanks for the future and I hope to get some answers.

Thanks,
Mazen

I am also running craftbukkit 1.6.4. Just if needed.

The error you are getting is probably because of the official minecraft authentication servers being down. A quick fix for this would be to change authenticate to false in your proxy config.

I second what @About7Deaths is saying, except don't turn authentication to false. It's just another security vulnerability.

I was just saying to turn it off as a temporary non public method. But if you are currently public I would not recommend this solution.

My server is also experiencing this issue, but other servers are not. Is there something hardcoded into Lilypad defining the IP of the auth servers? IDK if this helps, the caused by is java.nio.channels.UnresolvedAddressException

It doesn't matter if it is hard coded or not. The minecraft authentication servers keep offline (fake) players from joining your server. So when it is down, no one is able to join from lack authentication.
