我是JMeter的新手，所以我正在研究here教程，其中它指导我设置具有1个线程，1个加速周期和1个循环计数的基本请求。
我尝试访问指南中定义的网页，网址为www.tutorialspoint.com。
但是我的结果树每次都向我显示错误，如下所示：
Response code: Non HTTP response code: org.apache.http.conn.HttpHostConnectException
Response message: Non HTTP response message: Connect to www.tutorialspoint.com:80 [www.tutorialspoint.com/117.18.237.42] failed: Connection timed out: connect
当我在Fiddler上跟踪流量时，我从JMeter运行测试时看不到任何情况，这表明我什至没有到达网站。
不确定从这里开始我要去哪里。如果有帮助，我会在下面的请求和响应中添加更多信息。
采样结果：
