出现502 Bad Gateway，同一服务器上的网站没问题

ansley

我在一个服务器上建了多个网站，都是PHP+MYSQL，用DEDE建的这个站www.273m.com可以打开，用电影程序建的这个www.803d.com就打不开，出现502 Bad Gateway，
而我在PING这两个站的时候都出现了
C:\Documents and Settings\Administrator>ping 803d.com
Pinging 803d.com [149.255.36.25] with 32 bytes of data:

请问这个怎么解决？

还有，出现502 Bad Gateway的，我都按论坛里的一个个解决方法去试了，还是不行

Destination port unreachable.应该是iptables 屏蔽了ping

502可能是程序问题或虚拟主机的php解析配置问题
