Found out not to use port 22

[boco]

Port 22 is SFTP, completely incompatible protocol. FileZilla Server does not support it. Default port for FTP is 21.

Note that FileZilla will automatically attempt connection with the default port's correct protocol, so, if you try to connect to 22, it will automatically know to use SFTP. That's why you should refrain from using reserved ports for other uses. Reserved ports are all up to and including 1024.
