This is a server-side issue, whose cause is explained in the error message you've quoted.

You need to address this with the server's administrator.

Thanks for the reply.
Does it mean I have to contact the geodata website?

Yes, you have to contact whoever runs the FTP server. The contact address is hopefully listed in the website's Imprint.
