I have an issue with an FTP site for one of our clients, I need to configure it to use FTPS, I have setup the FTP site in IIS on Windows Server 2012 R2 and I have select the certificate I want to use under FTP SSL Settings, when I connect to it using WinSCP it says TLS Connection Established which looks good however a couple of seconds later I get the following error message:
I'm not too sure what is causing this because if I switch to just FTP with no encryption the connection works without issue, any ideas?Server sent passive reply with unroutable address <INTERNAL IP ADDRESS>, using host address instead.
Timeout detected. (data connection)
Could not retrieve directory listing
Error listing directory '/'.
