I think we can add ?ServerPassword=yourpassword to the launch parameters to set a password. Also there is a server config file we can access and edit via the FTP where you can set parameters from what I have read
Check out the other hosting companies. I think there is a bigger issue here as it seems most (if not all) of them are having issues bringing their Ark servers online. It's not just these guys. A better update would be nice, but I'd rather they spend the time getting the servers up an running!
