sftp connection question

[jeffreyren]

When I connect with sftp, it frequently reports:
Server unexpectedly closed network connection

If I refresh it again and again, sometimes it can work.
It seems sftp is very unstable.

Please attach some logs showing the problematic behaviour.

The logs should be made using debug level 3 which can be enabled
on the debug page in the settings dialog of FileZilla.

The logs have to be complete and unmodified. Do not attempt to
remove or obfuscate any information you might find irrelevant.

If you are worried about posting IP addresses or other
confidential information, mark the tracker item as private.

Are you using any firewalls? What happens if you completely uninstall them?

[jeffreyren]

It seems the question still can be found after I uninstall my firewall.
I will continue to pay attention to this question.

[Tim Kosse]

Are you sure you don't hit some sort of idle timeout? Like a certain period without file transfers on the browsing connection?

[jeffreyren]

Note sure. You mean when downloading, no browse action can be done?

[Tim Kosse]

Take a stopwatch, start a transfer and the stopwatch at the same time. Then measure the time until FileZilla gets disconnected. Write down the time. Repeat several times.
