I am testing the software to see if it will meet our needs. I have attempted to configure the FTP Server Settings for an FTP server that is running on the IBM i Operating System, V7R4 (aka AS/400). I can successfully connect with either Plain FTP or FTPS (implicit) using WinSCP and FileZilla. I have appropriate permissions, as I can upload files successfully with other FTP clients. However, I keep receiving the following error:
“The requested operation is not supported”.
I have turned on the “Trace” logging in the Advanced Log options. Please see attached picture for sample plain FTP configuration. If you would like to see the Trace log, please instruct me how to securely send it to you.
