FTP Transfer is not working in Active mode about fluentftp

[FanDjango]

I see the PASV command in the log. Show your source code. It seems you are not configuring the client right - because it should initiate an active connection, not a passive one.

@FanDjango Thanks for your response, please find below code for your ready reference:

var client = new AsyncFtpClient("localhost", "test", "test", 21, new FtpConfig() { ConnectTimeout = 2000, ReadTimeout = 2000 });
 
 client.Config.DataConnectionType = FtpDataConnectionType.AutoActive;
 var ftpConnect = client.AutoConnect(cancellationToken);
 await Task.WhenAny(ftpConnect, Task.Delay(2000, cancellationToken));
 
 if (!ftpConnect.IsCompleted)
 {
     _logger.LogInformation($"Timeout Occured for FTP Server:{item?.Server} Port:{item?.Port}");
     return;
 }
 
 var response = await client.UploadFile("test.txt", "/", FtpRemoteExists.Overwrite, true, FtpVerify.Retry, token: cancellationToken);
 if (response.IsSuccess())
 {
     _logger.LogDebug($"FTP Request Successful");
 }

[FanDjango]

client.Config.DataConnectionType = FtpDataConnectionType.AutoActive;
 var ftpConnect = client.AutoConnect(cancellationToken);

In this case you should use Connect(...) instead of AutoConnect(...).

The FtpDataConnectionType.AutoActive setting gets overwritten by AutoConnect(...).

[FanDjango]

The AutoConnect logic gets mixed up because it connects successfully and the the server says in the FEAT answer that it can do PASV, instead it hangs. Again: I recommend Connect(...).

Thank you so much @FanDjango, It's working now !!

One more possibility: Change the order of the statements:

var ftpConnect = client.AutoConnect(cancellationToken);
await Task.WhenAny(ftpConnect, Task.Delay(2000, cancellationToken));
client.Config.DataConnectionType = FtpDataConnectionType.AutoActive;

This should also work, I think.
