Upload file: requested action not taken #1641

FTP Server OS: Unix

FTP Server Type: Other

Client Computer OS: Unix

FluentFTP Version: 51.0.0

Framework: .NET 8

I am trying to upload a file. For some files the operation is successful. For others, an exception appears. Can you guess what is probably causing the problem? Can I have a better diagnostic than logging FtpStatus.Exception?

550 Requested action not taken.

Well. One promising google result tells me:

Some old FTP server doesn't support STOR /somefile syntax, you need to set CWD / and only then STOR somefile.

Try that maybe?

By the way: Think about the FluentFTP client "AutoNavigate" feature to make this "CWD" happen automagically.

Thank you for your suggestions. In the end it turned out that the server file is an old FAT and doesn't accept names longer than eight plus the extension. The problem is that neither the server nor client logs say much.
