    Ok, so I have CentOS installed, along with cPanel. I have a domain configured through Zone Edit to point to the server (http://www.politicaltension.com). I'm having a problem with 504 errors. The page loads normaly anf perfect, however every time the refresh button is pressed the 504 Gateway Timout error comes up instantly. Any ideas on how to solve this issue?

    Thanks

    What's the exact error message? Any errors in Apache's error log?

    BTW, are you sure that the DNS record for www.politicaltension.com is correct?

    Code:
    mh1:~# dig www.politicaltension.com
    
    ; <<>> DiG 9.2.1 <<>> www.politicaltension.com
    ;; global options:  printcmd

    The DNSservers are correct with my registrar. For some reason they seem to convert into the wfb.zoneedit.com DNS.

    This means that visitors to www.politicaltension.com will be directed to 69.72.142.98 or 216.98.141.250. I doubt this is correct. What's your server's public IP address?

    The public IP address is 209.89.95.165. HTTP traffic has been redirected to port 85 so 209.89.95.165:85 is the ip to get in (due to port 80 blocking on my DSL account). In Zone Edit, they have given me the DNS Servere of ns1.zoneedit.com and ns14.zoneedit.com. I logged into my registrara account, and can see that these are the entries for it.

    dnsstuff.com is showing these DNS servers, however they are then being redirected to a CNAME of wfb.zoneedit.com

    How I am searching:

    When you type www.politicaltension.com into your web browser and watch where your being sent to in the bottom left corner, it shows that you are being redirected to my servers IP address of 209.89.95.165:85

    This redirect is a problem if cPanel writes name-based vhosts to your Apache configuration (about which I'm almost sure). The domain should point directly to your IP address instead of being redirected. But then of course you will have the problem with your ISP blocking port 80.

    Anyway, are you absolutely sure your firewall doesn't block port 85, and that Apache is running on port 85? What's the output of
    Code:
    netstat -tap
    ?

    My firewall isnt blocking port 85. I was able to access the server without a problem for a day or two, then all of sudden this problem started happeneing. There were no changes to the system at all.

    netstat -tap provideds the following results

    I don't see Apache in the output, so I think it isn't running. Please restart it.

    I restarted httpd services, and its having the same issue. I even tried to restart the server, same issue.

    I get the following errors when restarting Apache. Does this have anything to do with it?

    root@server1 [/]# /etc/init.d/httpd start
    [Sun Nov 19 15:45:14 2006] [warn] VirtualHost 192.168.1.100:85 overlaps with VirtualHost 192.168.1.100:85, the first has precedence, perhaps you need a NameVirtualHost directive
    [Sun Nov 19 15:45:14 2006] [warn] NameVirtualHost 192.168.1.100:85 has no VirtualHosts
    /etc/init.d/httpd start: httpd started

    Once i have restarted Apach, if I type /etc/init.d/httpd status I get the following error message:

    root@server1 [/etc/httpd/conf]# /etc/init.d/httpd status

    Looking up localhost
    Making HTTP connection to localhost
    Alert!: Unable to connect to remote host.

    What's the output of
    Code:
     ifconfig
    ? What's in /etc/hosts?

    ifconfig shows the following

    The outputs look ok.
    Maybe it's trying to connect to port 80 instead of 85? Are you sure you replaced 80 everywhere in your Apache configuration?
