Receiving IllegalStateException on connect

[dyyd]

Built both Oger2 and Oger2-API.
Started the server with the command given in the README. (Used sudo since it wanted I believe port access or similar)
When connecting to the server from agar.io the server raises an "java.lang.IllegalStateException: Connection is not in CONNECTED state!" error.

Fuller stacktrace:
