I am having one strange
550 File Not Found Filezilla
problem that I've been trying to solve for past 2 days, but with no luck. Application that I've developed needs to upload one file to FTP address, and for that I used FtpWebRequest class. Everything seems OK until the code reaches GetRequestStream method, and hangs there until the timeout occurs. Here's the part of the code: FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpLocation + "/"+ the remote server returned an error (550) web deploy file.FileName); request.Method = WebRequestMethods.Ftp.UploadFile; request.UsePassive = false; request.Timeout = 10000; request.ContentLength = file.ContentLength; StreamReader sourceStream = new StreamReader(file.InputStream); byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); sourceStream.Close(); Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); requestStream.Close(); FTP location is supplied like this:ftp://user:pass@ftp.website.com/folder When request object is created, everything seems to be parsed OK, I've tried changing UsePassive mode, UseBinary mode, but no luck. Interesting thing is that I am able to connect to ftp and upload the file using some other FTP application, with same parameters! I used Network Monitor to track the packages, and saw that GetRequestStream method returns package like " Ftp: Response to Port 58963, '550 ' " with response code: '550, Requested action not taken'. (Before that, FTP gets response '150 Opening BINARY mode data connection' for request 'STOR folder\filename.extension') I've tried with different files of different types, none of them works. But, as I mentioned before, when I try to do the same thing using some FTP software, everything goes OK, so I suppose that it isn't firewall problem... Any ideas what might be the cause of this?
