can not connect to the server?

I want to connect to the server but there is error:10047

s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (s == INVALID_SOCKET) {
	WSACleanup();
	return;
}
sockaddr_in sock;
sock.sin_family = AF_INET;
sock.sin_port = htons(5000);
sock.sin_addr.S_un.S_addr = INADDR_ANY;
sock.sin_port = htons(5000);
bind(s, (SOCKADDR*)&sock, sizeof(sock));
listen(s, 5);
s = accept(s, NULL, NULL);
if (s == INVALID_SOCKET) {
	WSACleanup();
	return;
}

and then I connect it :

s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (s == INVALID_SOCKET) {
	WSACleanup();
	return;
}
sockaddr_in sock;
inet_pton(AF_INET, "127.0.0.1", &sock.sin_addr);
sock.sin_port = htons(5000);
if (connect(s, (SOCKADDR*)&sock, sizeof(sock)) == SOCKET_ERROR) {
	auto res = WSAGetLastError();
	WSACleanup();
	return;
}

it connect failed and return 10047 of WSAGetLastError();
