I have an FTP server that uses IIS 7.5, running on a Windows Server 2008 machine. When I try to connect to this server using filezilla with implicit TLS (ftps://), I always recieve this error:
GnuTLS error -15: An unexpected TLS packet was received.
The server connects fine when I don't use TLS (ftp://) or with explicit TLS (ftpes://) so I believe it is not a SSL issue.
Am I missing a configuration here?
Update: I was trying to connect to ftps using port 2122.
