Hello,

is this question too stupid, too basic? I won't press you to a solution - but I need to know whether I have to look for another solution for this. So I would appreciate any kind of information about this item.

Thank you,
Ulrich

This error is because the z/OS FTP client seems to be sending a SOCKS5 "BIND" command (2).
https://tools.ietf.org/html/rfc1928

This should not happen if you have specified "FWFRIENDLY TRUE" in your FTP configuration.

See: https://dovetail.com/docs/ftpsshproxy/install.html
