[Boost-users] Handshake Error 10009

Hello, I tried use the boost::asio to create a SSL-Server, but I fail. The Code I used is attached to this Text. acceptor_ and context_ give me true result, but the start_accept() methode give me a Handshake-Error: 10009 (invalid descriptor handle). How can I avoid this, and how can I fix the Code in the right point ?
