I suddenly get this error using SFTP:

Response: fzSftp started

Command: Pass: *********

Status: Retrieving directory listing...

Command: ls

Error: Connection timed out
Error: Failed to retrieve directory listing
I tried using FileZila, Cyberduck, Shell (Terminal), same result. However, it worked fine today (just a few seconds) in Passive mode.
I guess something changed in my network, so I have tried both: Active and Passive mode:

Because I'm working behind a router, I get my external IP from http://checkip.dyndns.org:8245/
I also tested different range of ports.
