title: Splunk showing gateway timeout
body: <p>We're running Splunk in our environment. We can only access the Splunk instance via the IP address, but not the DNS address we have mapped to it. </p>
  
  <p>For instance, we can go to this URL using the IP:</p>
  
  <p><a href="http://10.40.50.17:8000/en-US/app/launcher/home" rel="nofollow noreferrer">http://10.40.50.17:8000/en-US/app/launcher/home</a></p>
  
  <p>Splunk is working fine. However if I go to:</p>
  
  <p><a href="http://splunk.mycompany.com:8000/en-US/app/launcher/home" rel="nofollow noreferrer">http://splunk.mycompany.com:8000/en-US/app/launcher/home</a></p>
  
  <p>I get a gateway timeout error:</p>
  
  <blockquote>
    <p>Gateway Timeout<br>
    Server error - server 10.40.50.17 is unreachable at this moment.<br>
    Please retry the request or contact your adminstrator.</p>
  </blockquote>
  
  <p>I'm wondering where the issue may lie. Is this a problem with Splunk? Do I need to make Splunk aware of the DNS address that I'm giving it?</p>
