SSL_Accept失败，SSL_get_error返回1

Question

我是OpenSSL编程的新手。我的任务是编写一个可用的SSL代理。

但是，当我在Explore中启动代理时，ssl_accept()失败，错误代码为1。

为什么ssl_accept()失败？

int main(int argc, char **argv){
    checkArguments(argc, argv);
    initWSA();
    int port = atoi(argv[1]);
    struct sockaddr_in serverAddr = initAddr(port, std::string(""));
    SOCKET Client, Server;
    SSL_CTX *server_ctx = clear_method((SSL_METHOD *)TLSv1_1_server_method());

    if (!server_ctx)
    {
        ERR_print_errors_fp(stderr);
        std::cout << "ctx error";
    }
    load_certificate(server_ctx, "C:/Program Files/SnoopSpy/certificate/default.pem", "C:/Program Files/SnoopSpy/certificate/default.pem");
    open_socket(Server, serverAddr); //소켓 생성 함수
    SSL *server_ssl;

    while (true)
    {
        if ((Client = accept(Server, NULL, NULL)) == INVALID_SOCKET)
        {
            printf("error : accept\n");
            continue;
        }
        server_ssl = SSL_new(server_ctx); //설정된 Contexxt를 이용하여 SSL 세션의 초기화 작업을 수행한다.

        SSL_set_fd(server_ssl, Client);
        certificate(server_ssl, 0);
        char buf[BUFFER];
        memset(buf, NULL, BUFFER);
        recv(Client, buf, BUFFER, 0);
        cout << buf << endl;
