[04:20:04] [Server thread/WARN]: **** SERVER IS RUNNING IN OFFLINE/INSECURE MODE!
[04:20:04] [Server thread/WARN]: The server will make no attempt to authenticate usernames. Beware.
[04:20:04] [Server thread/WARN]: Whilst this makes it possible to use BungeeCord, unless access to your server is properly restricted, it also opens up the ability for hackers to connect with any username they choose.
[04:20:04] [Server thread/WARN]: Please see http://www.spigotmc.org/wiki/firewall-guide/ for further information.
[04:20:04] [Server thread/WARN]: To change this, set "online-mode" to "true" in the server.properties file.
