Hi!

FTP is an inherently insecure protocol. By default, unless FTPS is implemented, all credentials are sent in plaintext over an unencrypted connection. As a result of that, almost all FTP servers block root access entirely.

I would recommend uninstalling ProFTPD and connecting via SFTP, which is a completely separate file transfer protocol, that relies on SSH for authentication and encryption. You should be able to do that simply by setting your client to use SFTP and connect to port 22 and using your already existing SSH credentials to authenticate. Here’s a tutorial on using FileZilla to transfer files via SFTP.

Alternatively, if you absolutely need to use FTP, the ServerName directive only changes the text that appears when you connect to the FTP server, so that shouldn’t cause any errors. Try adding the following line to /etc/hosts and restarting ProFTPD:
