您的后端服务器未运行。您已配置后端主机“127.0.0.1”，但应使用“173.245.60.43”（webtelevideo.com 的 IP 地址）。
Your back-end server is not running. You've configured back-end host "127.0.0.1" but should have used "173.245.60.43" (the ip-address of webtelevideo.com).
当您看到此错误时，这意味着大多数情况下您的后端已关闭。 varnishlog 中的消息证实了这一点：Varnish log: 11 FetchError c no backend connection。
检查您的源服务器是否已启动并且 HTTP 服务（Apache/Nginx/其他）是否正在运行。
When you see this error that means most of the case your backend is down. Which is confirmed by your message in varnishlog : Varnish log: 11 FetchError c no backend connection.
Check your origin server is up and your HTTP service (Apache/Nginx/other) is running.
