注意：该应用程序已经工作了8个月以上，没有错误，但是只有在更新服务器上的窗口并重新启动后，我们才会出现此错误。

我尝试了以下步骤，但是它不起作用，并且出现相同的错误。

将Microsoft.Xrm.Sdk dll 8.2升级到9.0
替换了Microsoft.Owin.Security.OAuth.dll
创建了一个新应用程序
从“开发人员资源”中下载了最新的Organization.svc
在实例化OrganizationServiceProxy之前添加了代码行

ServicePointManager.Expect100Continue = true;
ServicePointManager.DefaultConnectionLimit = 9999;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // SecurityProtocolType.Ssl3;SecurityProtocolType.Tls11;
System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(delegate { return true; });

在O365管理员中检查了用户权限，并且具有完全访问权限。
证书仅有效。

谢谢
