无法连接到tomcat7

Question

我部署了.war文件的新版本，并且tomcat7也运行良好，状态显示给我：

root@s17298254:/var/lib/tomcat7/webapps# service tomcat7 status
 * Tomcat servlet engine is running with pid 11331

现在的问题是，我既无法查看网站，也无法在Web浏览器中查看管理器界面。请注意，它在生产环境中正在使用此tomcat实例。可能是什么原因？

[我已经尝试过许多操作，例如以root用户特权运行tomcat（虽然灾难灾难，但至少暂时无法使它工作），放置

useIPVHosts="true"

在<Connector>下等这是我的catalina.out：

它没有显示出任何致病性。所以我的网站现在不再工作是什么原因？

编辑：

我在浏览器中输入mywebsite.mydomain.net时出现的错误是：

Firefox无法在mywebsite.mydomain.net建立与服务器的连接。与Google chrome类似。

在tomcat 7中，在上下文元素下使用'xmlValidation'和'xmlNamespaceAware'。
