Ошибка Winsock 10049 пытается связать

У меня проблема с подключением к серверу. При попытке привязать сервер к IP-адресу моего внешнего устройства я получил ошибку winsock: 10049 Невозможно назначить запрошенный адрес. Использование локального сервера работает правильно.
Этот IP-адрес: 192.168.0.202 пинг успешно.
Я работал на win8.1. Я отключил брандмауэр и Windows Defender, и это не помогло.
