  • I believe you have to match the SDK to compile your application with the OS version for the Insider Previews. The Preview SDK is available from the developer section on Windows Insider.

    Jun 4, 2016 at 17:30

  • you get a timeout: WSAETIMEDOUT — A connection attempt failed because the connected party did not properly respond after a period of time, or established respond.

    Jun 4, 2016 at 19:30

  • I resetted my phone, installed the latest SDK, and set my project to target that SDK but it still fails

    Jun 5, 2016 at 14:30

  • It seems like a big issue in this Insider version. I wish Microsoft would write a public post on their blog about this, it seems quite serious

  • I’m using build 14385 and still getting the same error.

    Jul 12, 2016 at 15:15

  • So this issue is due to O.S Build target? I have the same issue here.

This is a known issue with the latest Windows 10 insider builds for Phone and a fix has already been submitted. You should be able to get this scenario working again by moving to the next insider build (what exact build number is still not known).

A workaround is to generate an .appx package and upload it using the Device Portal. You can activate the Device Portal on the phone from Settings -> «For developers».

У меня есть SSTP VPN с самозаверяющим сертификатом. Он работает на физическом экземпляре Server 2008 R2 в нашей локальной сети. Три рабочих станции вне сети запланированы для подключения к VPN «при запуске системы» в планировщике задач.

C:Windowssystem32rasman.exe -d "VPN Connection"

Обычно это работает без проблем. Я могу перезагрузить любую из машин, и соединение будет установлено.

проблема

Единственный раз, когда происходит сбой соединения, это когда машины выполняют свою ночную перезагрузку в 2:45 утра. Перезагрузка является еще одной задачей в планировщике задач:

C:Windowssystem32shutdown.exe -r -t 0

После этой перезагрузки Event Viewer показывает группы из двух ошибок:

  1. RasClient событие 20227

    Пользователь SYSTEM набрал соединение с именем VPN Connection, которое не удалось. Код ошибки, возвращаемый при ошибке: -2147014836.

  2. Событие RasSstp 1

    Первоначальный запрос протокола защищенного туннелирования сокета не может быть успешно отправлен на сервер. Это может происходить из-за проблем с сетевым подключением или проблем с сертификатами (доверительными отношениями). Подробное сообщение об ошибке приведено ниже. Исправьте проблему и попробуйте снова.

    Попытка подключения не удалась, потому что подключенная сторона не ответила должным образом через некоторое время, или не удалось установить соединение, так как подключенный хост не ответил.

Поиск проблемы

Что меня удивляет, так это то, что соединение прерывается только ночью. Я проверил запланированную перезагрузку в течение дня, и соединение всегда успешно. Я проверил настройки соединения и набрал номер вручную, и снова все прошло успешно. Это заставило меня задуматься, недоступен ли какой-либо компонент сети ночью, как предполагает описание события RasSstp. Тем не мение:

  1. Журналы событий сервера показывают, что он не спит и ведет себя нормально в 2:45 утра. В журналах ничего не говорится о получении запроса на соединение.
  2. Компоненты сетевого подключения (маршрутизатор, беспроводные антенны, брандмауэр, маршрутизатор и коммутатор к серверу) не имеют запланированных простоев. Может быть, они выходят из строя по какой-то другой причине, но кажется, что какое-то другое устройство из наших примерно 200 тоже будет жаловаться, если бы это было так.
  3. Результаты поиска ошибки -2147014836 сосредоточены на Windows Azure, которую мы не используем. VPN-сервер — это физический сервер в нашей локальной сети.
  4. Результаты поиска события RasClient 202227 сосредоточены на проблемах с установлением соединения, точка. Наша связь уже работает большую часть времени.

Вопрос

У кого-нибудь еще была такая ошибка? Есть ли что-то кроме сетевого сбоя, который может быть причиной этого? Ваша помощь очень ценится!

несколько дней назад было обновление для Windows Phone 10, и теперь я не могу развернуть свои приложения на свой телефон. Я продолжаю получать ошибку:
