版本 2025.1.0.0 升级后 不停的轮番报错401 和500，但也没影响业务功能，nacos服务端版本2.3.2
另外一个服务同配置也没这个情况，另外这个服务测试环境也没这个问题，问AI 说是 监控检查 引起的
nacos配置

    nacos:
      discovery:
        server-addr: ${NACOS_ADDRESS}
        username: ${NACOS_USERNAME}
        password: ${NACOS_PASSWORD}
        namespace: ${NACOS_NAMESPACE}
        service: ${spring.application.name}
        cluster-name: DEFAULT
      config:
        server-addr: ${NACOS_ADDRESS:nacos:8848}
        username: ${NACOS_USERNAME}
        password: ${NACOS_PASSWORD}
