Push-уведомление Apple получает сообщение об ошибке Аутентификация не удалась, поскольку удаленная сторона закрыла транспортный поток

Я получаю следующую ошибку "Аутентификация не удалась, поскольку удаленная сторона закрыла транспортный поток"

после кода ling: stream.AuthenticateAsClient(this.appleSettings.Host, this.certificates, System.Security.Authentication.SslProtocols.Ssl3, false);

Это указывало на действительный стр. 12
