如日志所示，ChromeLauncher 拒绝连接到 Jenkins。您可能想检查是否允许 Jenkins 访问此正在运行的服务。

如果您的 ChromeLauncher未在 headless 模式下运行，或者 ChromeLauncher 的多个实例正在运行，并且没有剩余可用端口，也会发生这种情况。 p>

您可以尝试将以下内容添加到您的 ChromeLauncher 启动配置中。事实上，你应该提到这些。

chromeOptions = {
        chromeFlags: ["--disable-gpu", "--headless", "--enable-logging"] 
}

查找此here 的更多详细信息。

作为替代方案，您可以考虑在 Docker 中运行 Lighthouse，以将其与 Jenkins 隔离。这样，您可以扫描您的项目，生成 HTML 报告并将其发布回 Jenkins。

您可以按照here提到的方法。
