Format the LastErrorText in "pre" tags so that it's readable...


First, you are using an old version of the library, so I recommend updating to the latest version and trying again.

If the problem persists, can you give us some more information about what you are trying to do that is failing? Maybe a code sample? All we have now is an error log.

That said, the error indicates that there is no connection to the server. So have you tested for success on previous method calls to make sure that an earlier call hasn't disconnected you from the server for some reason?


Here my code what i am doing for get the connection and write the file in document directory please have a look.

     self.chilKatFTPManager=[[CkoFtp2 alloc]init];
     self.success= [self.chilKatFTPManager UnlockComponent: @"Anything for 30-day trial"];
     if (success1 != YES) {
     [strOutput appendFormat:UNKOWNN_DOWNLOAD_ERROR,remoteFilename];
      [self showChilkatError:strOutput];
    self.chilKatFTPManager.Hostname = appdelegate.strFTPHost;
    self.chilKatFTPManager.Username = strFTPUserName;
    self.chilKatFTPManager.Password = strFTPPassword;
    [self.chilKatFTPManager setSkipFinalReply:YES];
    [self.chilKatFTPManager setPassive:YES];
    [self.chilKatFTPManager setPort:[NSNumber numberWithInt:21]];
    self.success2 = [self.chilKatFTPManager Connect];
    if (success2 != YES) {
      [self showChilkatError:strOutput]; }
     BOOL success= [self.chilKatFTPManager GetFile:remoteFilename localPath:filePath];


It appears the connection is being dropped before Passive mode can be set. Some things to try/consider:

  1. Did you upgrade to the latest version of the library and try again?
  2. Set VerboseLogging = 1 to get more information in the LastErrorText property, and then repost it here in <pre> tags.
  3. The documentation for SkipFinalReply says only to use if advised by Chilkat to do so. Are you sure your FTP server requires this property to be set?


The connection will only break for one of a few reasons: a bug in the Chilkat library, a bug in your code, bad configuration of the properties in your code, the server decides the connection should be closed for some reason, or network hardware or configuration problem.

Let's assume that your network hardware and configuration is correct. Let's also assume that your code is bug free.

That leaves a possible bug in the Chilkat library, which is why I suggested upgrading to the latest version (9.5.X). Did you do this and try again?

It also leaves bad configuration of the object properties. I asked if you were instructed to set SkipFinalReply:YES by Chilkat, since the documentation states that you should only do so if instructed. If not, have you tried with SkipFinalReply:NO?

Lastly, it's possible that the server is deciding to close the connection due to conditions that are not clear (security configuration? bug on the server?). This is why I suggested setting VerboseLogging:YES and reposting the LastErrorText contents at the point of failure, as there may be more information that will help diagnose the problem.
