FreeFileSync Forum

Update:

When I add another static route in Windows for the VPN subnet, freefilesync stfp function appears to be able to connect to the ssh host. Odd, that I do not need to add the static route for any other sftp client to successfully connect like putty, or winscp, etc.

Update2:

After a few days ...

I have recieved this same error, with multiple network adapters. In my case it is the OpenVPN adapter which routes traffic to the SSH server through a VPN.

I can access the SSH server via other SFTP clients.
