我有USER_TOKEN_POLICY_USERNAME启用并用于UsernameIdentityValidator设置用户名和密码的 milo opcua 服务器。

从 milo 客户端，我习惯于UsernameProvider设置setIdentityProvider.

当我运行此设置时，一切正常。

但是当我重新启动 opcua 服务器时，milo 客户端不会重新连接。我遇到了以下异常：

我认为从您的新日志中提取的有意义的异常是：

io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: /192.168.56.101:4840

简单的网络错误。服务器不存在，没有运行，防火墙挡住了，等等......

您现在在客户端代码中没有做错任何事情。

似乎客户端/服务器证书验证存在问题。

UA PKI、X509等复杂难懂，更难正确配置，几句话无法回答。如果您刚开始使用 OPC UA，请尝试跳过服务器策略和用户标识，直到您了解为止。

服务器和客户端将需要证书才能解密或加密用户身份验证。

但是做一些检查：

  • 检查客户端是否在其受信任的路径中具有服务器证书。
  • 检查服务器证书是否已更改。服务器不应在每次服务器启动时重新生成其自签名证书，而只能在安装设置或管理时重新生成。

解决方法：
