This is a c+p of my post on the winscp support forums:

 

 

 

Version: 4.17 (Build: 413) on Windows XP SP2

 

 

 

I use the GUI Commander interface, and run SFTP protocol v5, Keepalives 5s interval dummy commands, no compression, SSH protocol v2, Blowfish cipher.

 

 

 

Problem: Experiencing "How has not answered for more than x seconds. Still waiting..." - On DOWNLOADS ONLY.

 

 

 

Randomly started having this problem. Uploads to the same remote location are not affected at all, however I have to stay where I am so I can click 'Abort' then 'Reconnect' every x seconds whenever I get a timeout so I can keep downloading a file. File size is irrelevant, I have regularly download and/or uploaded files between 1kb and over 2gb. All of them have suffered from this 'timout' problem and I have no idea what is causing it.

 

 

 

Server settings haven't been changed, local settings haven't been changed. It just stopped .. working, I guess.

 

 

 

Almost a dozen people share the same ini file, and none of them have download problems. Just me. This [cabbage] just started randomly one day without anything being changed, anywhere. Locally, server, isp, nothing. And I am absolutely stumped as to why it is affecting my downloads only. I would've assumed that a timeout which affects transfers FROM a location would occur when a transfer is made TO that same location, but this isn't the case :wall:

 

 

 

And, as you can imagine, I can't afford to be sitting at my desk all day, click 'Abort' then 'Reconnect' on a 1gb+ download when it timeouts at least once a minute.

Maybe a setting in your firewall? Although I think it wouldn't let you transfer at all if it was that, but still worth checking.

No firewall.
