FTP TLS Explicit Encryption Problem
I've spent many days trying to resolve this with info from documentation, forums, google at large. I signed up to post my issue downloading a file via FTPS w Explicit TLS Encryption (Data and Control) and encountered an unexpected different issue.
Successful Connection via CoreFTP GUI, directories/files are visible:
Successful Connection via FileZilla GUI directories/files visible:
Connection successfully made but directories/files unavailable in GUI
I was pretty amazed to see the log actually list the directories/files, however I still can't 1) see them in the GUI 2) GET them.
Thanks, I hope I've provided enough information.
