Re: Upload fails for plain FTP

I assume that your DestPath value does not have the correct syntax.
It should be like /remote/path/dir/ or /remote/path/dir/*, while you are probably using /remote/path/dir.
See https://winscp.net/eng/docs/library_session_putfiles#remotepath
and https://winscp.net/eng/docs/faq_script_vs_gui#inputs

Alternatively, use Session.PutFilesToDirectory, which is not that strict:
session.PutFileToDirectory(Path.GetFullPath(SourceFileName), DestPath, false, transferOptions);

If this doe not help, please post more specific example with actual paths, not just variables. And code and log for your working FTPS session.
