C# 发送IOS推送通知时出现PushSharp错误消息

我也有同样的问题。我不是IOS开发者，但我是c#开发者。iOS开发人员给了我一个配置文件，以便在我们正在运行的windows服务中发送推送通知。我用我的iPad测试了PushSharp，但它不起作用。我收到了错误消息：

推送通知失败：PushSharp.Core.MaxSendAttemptsReachedException:已达到发送通知的最大尝试次数

我已经在本地和服务器上尝试过，我只尝试发送一次推送

我也在使用windows server，我能够解决这个问题。见“及”。通过重新生成我的证书，两者都得到了解决

push.RegisterAppleService(new ApplePushChannelSettings(appleCertificate, "PASSWORD!"));
push.QueueNotification(new AppleNotification()
