I tried to Man-in-the-middle attack with C, success get HTTPS target host, SSL_connect to the server and create fake certificate success, when I try to SSL_accept client socket, it's failed and SSL_error: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

 int socket_to_server = open_client_socket(p->client, p->host, p->port);

    // create ssl connect by server socket

    ssl_to_server = SSL_to_server_init(socket_to_server);

    if (SSL_connect(ssl_to_server) < 0)

        SSL_Error("Fail to connect server with ssl!");

    printf("%d, SSL to servern", sum);



    // get server cert and fake 

    fake_x509 = create_fake_certificate(ssl_to_server, p->key);

    // use fake cert create client SLL connect

    ssl_to_client = SSL_to_client_init(p->client, fake_x509, p->key);



    if(ssl_to_client == 0)

    {

        SSL_Error("SSL to client Failed!n");

    }

    if (SSL_accept(ssl_to_client) <= 0) // failed there, error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

        SSL_Error("Fail to accept client with ssl!");
