Hi Windows 8.1 with FileZilla - latest Version - can't upload files. Error Message: Response: 150 Opening BINARY mode data connection. Response: 550 The supplied message is incomplete. The signature was not verified. Error: File transfer failed I don't tested other Tools like WinSCP. I work years with FileZilla and i don't look for a new Tool, without a serious reason. Thank you for your help. Greetings Peter
To resolve that error message you need to use the option "Use plain FTP" Read our knowledge base article here: https://support.Winhost.com/kb/a660/configuring-filezilla-to-access-your-web-site.aspx See the section "Use plain FTP".
