FtpWebRequest TLS session of data connection has not resumed or the session does not match the control connection RRS feed

  • Question

  • I have everything up to date and the issue is not resolved.

    When I turn off "Require TLS session resumption..." it works.

    Server log:

  • Hello hbatrnek,

    Based on your description, I am afraid that the issue is out of support of C# general question forum which mainly discusses C# programming language, IDE, libraries, samples and tools. I suggest that you can consult your issue directly on FileZilla Forums for better solution and support.

    Best regards,

    Neil Hu

  • I doubt that is a problem with FileZilla, they will probably just say that it is up to FtpWebRequest. Are you sure this is not the problem with FtpWebRequest? I think it is because recently you had a bug in HttpRequest regarding TLS resumption and I have all the updates.
