您可以使用“节点跟踪器”插件。这个插件允许Jenkins跟踪断开连接的节点，并在节点再次可用时自动恢复构建。
如果Node Stalker插件不能满足您的需求，或者您更喜欢其他方法，您可以使用Jenkins Pipeline和Groovy Script实现自定义解决方案。

pipeline {
    agent { label 'your-node-label' }
    stages {
        stage('Run Tests') {
            steps {
                script {
                    try {
                        // Your Selenium test execution command or script here
                        sh 'your-selenium-test-command-or-script.sh'
                    } catch (Exception e) {
                        echo "Node disconnected! Waiting for node to come back online..."
                        nodeWait()
                        echo "Node is back! Resuming test execution..."
                        // Retry the Selenium test execution command or script here
                        sh 'your-selenium-test-command-or-script.sh'
                    }
                }
            }
        }
    }
}

def nodeWait() {
    // Wait for the node to come back online, check its status every 10 seconds
    timeout(time: 30, unit: 'SECONDS') {
        waitUntil {
            return isNodeOnline()
        }
    }
}

def isNodeOnline() {
    // Check if the node is online
    def node = Jenkins.getInstance().getNodeByFullName('your-node-name')
    return node != null && node.toComputer() != null && node.toComputer().isOnline()
}
