FileZilla should pause at failed transfer

[TAB42]

If I download a directory —maybe 1000 files —, some transfers fail (ECONNABORTED), flashed in red, but so briefly that I cannot even read the message.
Why does FileZilla not pause to show what transfer failed and let me decide what to do?

It does not stop because it automatically retries the transfer. Usually, all transfers succeed, despite of some errors (quite normal for FTP).

Transfers that truly failed (permanent errors requiring user interaction) are moved to the "Failed transfers" tab, from where you can re-queue them, once you have removed the reason for transfer failures.

I transferred a directory: successful, 11013; failed, 82. I clicked 'Failed transfers (82)' without result —no list, no offer to re-queue them.
'Some errors are quite normal for FTP' —Really? How do I know if some of these 82 files were not critical to the operation of my website?

Have you by change resized your queue panel to be so small to only show this one line instead of all of it?

Indeed. As FTP uses, for transfers, a multitude of ports on both sides of the connection (different from the ones you use initially to connect), some errors are normal (4.. = temporary). A port might be blocked, closed, or otherwise not being available for use. FileZilla will automatically retry and the server uses a different port,then.

Your errors (the ones in Failed transfers) are permanent errors. These are NOT normal, and you need to find out what happens here. Having anything in "Failed transfers" means that either the server denied the items completely (sending a 5.. error = permanent, won't recover on its own), or FileZilla has exhausted all retries for each of them.
