    I am new to debugging traffic, I trusted the certificate to decrypt https traffic for all applications that use the trustlist from windows.

    My target application however (or the server it connects to) doesn't work like that.

    I have really no clue why, some intuitive suggestions:

     

    CONNECT osu.ppy.sh:443 HTTP/1.1
    Host: osu.ppy.sh
    Connection: Keep-Alive

    A SSLv3-compatible ClientHello handshake was found. Fiddler extracted the parameters below.

    Version: 3.1 (TLS/1.0)

    =================================================

    POST https://osu.ppy.sh/web/osu-error.php HTTP/1.1

    System.Exception: SSL failures

       at [..........................]

     

    So, I do have the standard configuration in fiddler which is <client>;ssl3;tls1.0 and since the server seems to be tls1.0 it should work, right?

      

    Thank you so much in advance!
