IOException in Put over certain file size

Question

Hi, i have been successfully using this FTP object for some time but have found that i am consistantly getting the following error if the file being sent is over 10MB.

IOException in Put(string,string,bool) : System.IO.IOException: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I can send the same file using WS_FTP for example with no issues.

Is there a limit on the free version?

Here are some of the configuration settings i have..

ftpClient.RemoteHost = ftpSite;
ftpClient.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.PASV;
ftpClient.CloseStreamsAfterTransfer = true;
ftpClient.SynchronizePassiveConnections = true;
ftpClient.Connect();
ftpClient.User(ftpUsername);
ftpClient.Password(ftpPassword);
ftpClient.TransferType = EnterpriseDT.Net.Ftp.FTPTransferType.BINARY;
ftpClient.BytesTransferred += new EnterpriseDT.Net.Ftp.BytesTransferredHandler(BytesTransferred);

Cheers
Grant.

Answer 5

Hi, I uploaded a 5 MB file (a smaller one because I'm uploading from the Internet) which took about 5 minutes. There wasn't any problems with timing out.
