Topic "FTP with implicit SSL connection disconnects"

I am currently making a connection that is having random disconnects.

using passive port range of 1024-1224

It seems that everytime your client goes from passive port 1080 to 1081 it disconnects from the site. My firewall shows no attempt to go to passive port 1081 the connection just dies there. I have testing this on both your current beta build and current stable release.




heres some info from your logging some data has been changed for privacy reasons.




Thanks!!

I have found the problem it was not related to WINSCP our Websense filtering was blocking the port ....


Thanks
