The browser indicates that it is contacting the host and then times out with the following message:
The document contains no data; Try again later, or contact the server's Administrator....
Make sure that the system is configured correctly and that Content Gateway can read the name resolution file.
*
Use the nslookup command to confirm that the server can resolve DNS lookups. For example:
nslookup www.example.com
*
Confirm that /etc/resolv.conf contains the valid IP address of your DNS server(s).
*
On some systems, if the /etc/resolv.conf file is unreadable or has no name server entry, the operating system will use localhost as a name server. However, Content Gateway does not use this convention. If you want to use localhost as a name server, you must add a name server entry for 127.0.0.1 or 0.0.0.0 in /etc/resolv.conf.
 
Important 
If the IP addresses in /etc/resolv.conf change, Content Gateway must be restarted.
