I noticed that this was a bug error message in an older version (this is my first time using WinSCP), and it was apparently fixed then. However, I'm receiving this when I attempt to log in to my FTP (standard, not SFTP).
Actually, I was able to log in last night without issues, but no longer. Additionally, I am still able to log in with other software, so I don't think it's a server problem.
It occurs while attempting "Reading directory listing..."
Is there any information I can give you to help with this?
