My clan lost a man who set up our ts3 to cloud. He died. And now i try to transfer new license key to cloud server. Our host provider has no ftp and all must do on debian console. I do not know how to do that.
Yes, i m sure that it the thing but i try , no any progress.
Try Filezilla with sftp, its using the ssh port.
