    Hello All,
    Having a problem with my FTP client that I've built with Qt 5.15.2. This client will update the .bin files of the Ubuntu FTP server. So far;

    • I've installed an FTP server on Ubuntu 20.04 with VSFTPD, tested it with FileZilla both with username/password and anonymously. It's working well.

    • As a second step, I've built an FTP client with Qt 5.15.2 QNetworkAccessManager, tested it with a web-based FTP server, and connected without any error message. Uploaded a random file.

    • Finally now, trying to connect with my FTP Client to the Ubuntu server with no success. Receiving the below error message:
      QNetworkReply::ContentOperationNotPermittedError

    Do you have any suggestions about it? Is there any chronic issue with Qt for FTP clients/servers? Especially local ones?

    Thanks in advance.

        Thanks for your reply, I have used the QUrl with and without the file name in it. None of them had success. But I haven't tested QFTP. And I'm not sure if this advice is for speeding up the QFTP or making work QNetworkAccessManager? Should I come to terms with the QNetworkAccessManager version never works?

          I'm having a similar issue with NetworkAccessManager uploading a file to an FTP, i'm getting "QNetworkReply::ContentAccessDenied".
          Have you found a solution?
