For the connection I am using FTP with TLS Explicit in passive mode with keepalive of 30 seconds.
This is my script:
option batch on
option confirm off
option transfer binary
synchronize local C:\SITE -delete
Everything has been working fine for months until I installed some web apps to the FTP server with 100's of files and many folders (wordpress/gallery etc).
Now I get this error in the console 3 minutes into the synchronization:
Disconnected from server
Could not retrieve directory listing
Accepted data connection
Error listing directory '/xxxx/xxxx/xxxx/xxxx/xxxx'.
Session 'XXXX@X.X.X.X' closed.
This only occurs after 3 minutes of traversing directories which did not need updating on the local machine. When run the first time, when the local directory is empty, I do not get this problem.
When I disable the Windows Firewall entirely the synchronize works. However, with the Windows Firewall turned on and no matter what settings I seem to try I always get the problem.
I am not a windows firewall expert but in testing I have tried:
1. Allowing all connections for WinSCP.exe and WinSCP.com
2. Telling the firewall to 'Allow' for all inbound connections, to any program (configured in 'Advanced Settings>Firewall Properties>Private Profile' of Windows Firewall).
3. Telling the firewall to log dropped packets (the log remains empty).
The error only seems to go away when I completely turn off the firewall ('Advanced Settings>Firewall Properties>Private Profile>Firewall State>OFF').
The firewall log does not show any dropped packets, which is confusing me.
What are the correct settings to overcome this issue?
Thank you for such a great program. Any help appreciated :)
