Я хотел протестировать простой сервер OPC-UA с UaExpert.Сервер работает, и когда я пытаюсь подключиться к серверу с помощью UaExpert, я продолжаю получать следующие сообщения
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'.
Я использую предоставленный сервер ExampleServer и подключаюсь к серверу без политики безопасности и анонимной политики.
Кто-нибудь может помочь?
