Using FileZilla (latest version), if I do NOT use SSL, things work fine. If I use SSL, I can connect, view and delete, but I can't copy new files to the server. If I try to copy to server, it looks like it tries about 3 times then gives up. The messages at the top show: Response: 150 Opening ASCII mode data connection. Response: 550 The supplied message is incomplete. The signature was not verified. Error: File transfer failed My connection information looks like: ftp.w06.wh-2.com Protocol: FTP Encryption: Require explicit FTP over TLS Is there a way I can upload files with FileZilla and SSL?
Yes. Use an older version of FileZilla (no later than 3.9.0.6). There's a problem with newer versions of FileZilla and how they connect to IIS using TLS. Or use another FTP client like CoreFTP.
