Solved Messaging channel not working

Code (Java):

    public final void connect(Player player, String server) {
        ByteArrayOutputStream b = new ByteArrayOutputStream();
        DataOutputStream out = new DataOutputStream(b);
       
        try {
            out.writeUTF("Connect");
            out.writeUTF(server);
        } catch (IOException e) {
        }
        player.sendPluginMessage(Main.getPlugin(), "BungeeCord", b.toByteArray()); // ERROR HERE
    }

So I was trying to allow players to connect using this but it doesn't seem to work, yes the server I have it with actually exists so it should be working. What am I doing wrong? The plugin is not null.

 

Thanks, fixed
