问题描述
由于无法访问证书私钥异常，我的OPC UA服务器无法启动。这确实让我感到困惑，因为我正在使用AnonymousUserTokenPolicy。上次我运行服务器时，一切正常。我没有更改配置文件，也没有相关代码。我花了数小时在OPCFoundation上搜索，但没有成功。有人可以帮我吗？预先感谢。
这是我的配置文件：

我用来启动服务器的方法（它在BackgroundWorker中运行）
private void InitServer()
{
ApplicationInstance app = new ApplicationInstance
{
ApplicationName = "RoboBar.TestServer",ApplicationType = ApplicationType.Server,ConfigSectionName = "RoboBar.TestServer"
};
try
{
var configuration = app.LoadApplicationConfiguration(false);
var certificate = app.CheckApplicationInstanceCertificate(false,0);
certificate.Wait();
var certOK = certificate.Result;
if (!certOK)
{
throw new Exception("Application instance certificate invalid!");
}
var startServer = app.Start(new RoboBarServer());
startServer.Wait();
}
catch (Exception ex)
{
string text = "Exception: " + ex.Message;
if (ex.InnerException != null)
{
text += "\r\nInner exception: ";
text += ex.InnerException.Message;
}
MessageBox.Show(text,app.ApplicationName);
}
Server = app.Server as StandardServer;
Configuration = app.ApplicationConfiguration;
}
任何帮助将不胜感激。
