i get this error when i try to join my clients server or whenever anyone joins for that matter. Here is a little picture of the error

On the mc client all it says is "Authentication to minecraft.net failed"

know what might be causing this? any help would be appreciated

Here is the proxy.yml in code:

You are using a outdated proxy. http://ci.lilypadmc.org/job/Go-Server-Proxy/ update to 74
