scFTPClient: Active-Connection ListDir -> ErroNo.: 530 ..Please login with USER and PASS

scFTPClient: Active-Connection ListDir -> ErroNo.: 530 ..Please login with USER and PASS

SBridge Version 10.3.1

Following scFTPClient-properties are defined:
Hostname, Username, Password, UsePassive true/false (makes no difference)
TLSMode = tmDisableTLS

Connect
Active = true

when calling ListDir, the error occurs.

What's wrong.

I can't find any examples for using this component.

The problem is very urgent.

Thanks in advance
