我想用UaExpert测试一个简单的OPC-UA服务器。服务器已启动，当我尝试使用UaExpert连接服务器时，我一直收到以下消息
18:18:48.633 | Server Node | test | Endpoint: 'opc.tcp://DESKTOP-ss:12686/test'
18:18:48.633 | Server Node | test | Security policy: 'http://opcfoundation.org/UA/SecurityPolicy#None'
18:18:48.633 | Server Node | test | ApplicationUri: 'com:test'
18:18:48.633 | Server Node | test | Used UserTokenType: Anonymous
18:18:48.633 | Server Node | test | The server returned no certificate, all certificate checks will be skipped.
18:18:48.664 | General | | Error: UaSessionPrivate::activateSession - no endpoint matching the session security settings
18:18:48.664 | Server Node | test | Error 'BadConfigurationError' was returned during ActivateSession
18:18:48.664 | Server Node | test | Connection status of server 'test' changed to 'Disconnected'.
我正在使用提供的ExampleServer，并在没有安全性和匿名策略的情况下连接到服务器。
有人可以帮忙吗？
我的代码如下：

我无法复制您遇到的确切问题。使用未修改的示例服务器和名称空间，UaExpert可以毫无问题地连接。
由于您的命名空间实现不完整，因此使用代码会出现一堆超时错误。
