  • die Frage ist:
    Stimmt was mitt der Syntax der Anfrage nicht ?
    oder mach ich im Code irgendwas falsch ?
    Vielen Dank f├╝r eure M├╝he


  • Mod

    Die Antwort steht in der Fehlermeldung.

    Du kannst auf dem HTTPS Port keine HTTP Anfrage hinsenden. Du musst das schon korrekt mit SSL/TLS Verschl├╝sseln. Dein Websniffer wird das Transparent f├╝r dich machen.



  • Herzichen Dank!
