Problems with file upload

Hello,
I'm experiencing problems with uploading some files.
The files got added to the transfer queue but the upload doesn't finish. SmartFTP retries uploading the files several times and then it cancles the upload.
Sometimes it works after several tries but often it fails.

I'm connection over "FTP over SSL Explicit". Uploading with an ordinary ftp connection works.

Here is the ftp log:
[14:14:27] SIZE table.xls

[14:14:27] 550 table.xls: No such file or directory

[14:14:28] The operation has been added to the Transfer Queue. Check the

Transfer Queue for the status.

I contacted my web hoster and asked for the server log entries:
Link to file server lost

I'm using SmartFTP 3.0.1024.32 on Win XP Pro SP2.
Some weeks ago there weren't any problems.

Thanks.

Install the latest version of SmartFTP from here:
https://www.smartftp.com/download

Then post the log from the transfer queue item. To get it just double click the file in the transfer queue.

[17:04:01] Max retry (11 of 10) reached.

I think the problem is with the server. It says that it lost the connection to the file server. It doesnt say it lost the connetion to the client (your computer).

I recommend you set the max retry to a value higher than 10.

Hello,
I've tried it with Filezilla several times. Used the same server, the same login credentials, the same connection options and the same files to upload.
And it worked without problems.

Also a webclient (www2ftp) throwed no errors.

Increasing the max retries didn't changed anything except it tooks longer to cancel the transfer.

Regards,
jan.itor

www2ftp does not use encrypted data transfers so it's not a good argument. Post the log from Filezilla.

Do you have Netlimiter installed?

And please post the system information from the menu: Help->About "System Information" in SmartFTP.

You got it!

The problem was an enabled upload limit for SmartFTP.
Do you have an idea why this results in the problems? Does NetLimiter delay responses which causes SmartFTP to think the connection was lost?

Thanks for the quick support!

I have no idea why Netlimiter causes the problems but it seems the problem (with Netlimiter) has been around for years according to the google search results I have found.
