File transfers incomplete

#1 Post by piperson » 2023-03-19 17:49

Since rebuilding my Operation System from Win 10 to Win 11 on a Dell XPS8930 and upgrading to the latest FileZilla release (3.63.2.1), my file transfers are not completing. They are timing out with just a few percent actually being transferred. No error messages are presented.
On a different Win 11 PC, on same home network, the same transfers are working properly.

I need a clue to adjust this application.

Here is the log: The file to be transferred is 1,212,416 bytes

Set to "Ask for action" downloads and Uploads.

Furthermore, another PC on the same home network with Win 11 and the latest Filezilla has no problem transferring the same files.

Some misbehaving firewall perhaps? Other than that I'm out of ideas.

More info.

The problem PC is a Dell XPS8930 Win 11 and is Cat-5 connected to the Router. Provides incomplete Xfers.
The other PC is a Dell Inspiron 15 Win 11 Wifi connected to the same router Router. Xfers properly.

Both PC's have the latest Filezilla version and setting are as installed.

It seems that after upgrading to Windows 11 and installing the latest FileZilla release, file transfers are timing out and only a few percent of the file is actually being transferred. The log provided shows that the connection timed out after 20 seconds of inactivity.

One possible reason for this issue could be a weak connection. Since the same transfers are working properly on a different Windows 11 PC on the same home network, it may be worth checking the connection on the affected PC. A weak or unstable connection can cause file transfer issues, such as timeouts or incomplete transfers.

To address this issue, you can try the following steps:

Check the network connection on the affected PC. You can try restarting the router or modem, or resetting the network adapter on the PC.
Make sure that the firewall or antivirus software is not blocking the FileZilla application.
Try using a wired connection instead of a wireless connection, or vice versa.
Try transferring the file using a different FTP client to see if the issue persists.
If none of these steps resolve the issue, it may be worth seeking further assistance from a technical expert or the FileZilla support team.

I have a similar issue, where a file completes transfer to my server, but FileZilla shows as having queued files remaining. Yet the file on server looks complete and functions properly. Any thoughts much appreciated.

Maybe you have it queued more than once, by accident?

You can always right click the queue pane and select "Stop and remove all", to start with a clean slate, next time.

I have same problems with Filezilla when use multiple streams each downloading their multiple files in parallel (say you download many files in some directory).

How Filezilla is doing here? Filezilla just rush like crazy and does not care if the files were completely finished, it just keeps downloading other files. If it thinks that the specific stream is not responding or busy, it tries it few times and then (if eventually failed by some reason) it forgets this file leaving it incompletely downloaded and takes another file to download. 5-8 years ago in Windows Filezilla was working OK, but now i tried it in Linux, its GUI looks nice but over last few years I always failed: FZ finishes downloads and ALWAYS leaves you with multiple broken partially downloaded stuff.

WinSCP never leaves you with partially finished files. Even if some streams fail there, stall not responding for a long time etc other streams will take unfinished files eventually later and will complete stalled streams. So i am still forced to go to Windows and use WinSCP (which does not work on Linux or on WINE under Linux)

Just copy what and how WInSCP handling downloads and Filezilla will have 10x times more users.

May be i set something incorrectly?
I use Linux Mint

Failed transfers are not forgotten, they are placed in the failed transfers tab of the queue, from which they can be re-queued.

Well, my impression is that the authors are not familiar with 2-factor authentication like Duo now used everywhere. In every university for example it is a default. Because of defect of Filezilla i described in previous post it always miss 3-4 of downloads when you try to download all 9 streams in parallel allowed by the settings (9). That happens because you have to authorize initially all of them with Duo when download starts. The Filezilla does not care that it takes a half of a minute to click on Duo and places several of these 9 files into Failed Transfers.
https://i.postimg.cc/BbqkpHgR/Failed.png
When re-queued, the 1-2 of these 5 failed downloads will again fall and get into failed transfers.

Even worse things happen when you download large directories. With any small hiccup and delay in the network the FZ drops current stream and starts new file download. Then become a total disaster. Because we have many shousands of files sometimes (not uncommon nowadays ), approximately few percents of them will fail to download which could be still thousands of files. When you will try to download these failed files from Failed folder then again few percents of them fail. You may not notice that thinking all was downloaded and will end up with broken downloads.

( And total disaster was few years ago, when FZ refused to place ones failed downloads into Failed Downloads folder second time and you 100% were losing files in this case, i did not check lately if this still happens with latest Filezillas)

Definitely this behavior has to be fixed somehow. Filezilla always have to finish download and check automatically that every bit of initial directory was downloaded safely
