If it works, can you check there is no device in traffic path blocking TCP 443 to IPS? Can you do a capture on IPS to see if request on TCP 443 is indeed reaching the IPS?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-&lt;/P&gt;&lt;P&gt;Sourav&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;P&gt;Hello.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I'm trying to get event logs from my ips 4510 into splunk.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;When I add the host on which splunk is running as a "trusted host" I get the error:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Cannot add #.#.#.# as a trusted host.&amp;nbsp; errTransport-socket connect failed [4,111]&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;There are no firewalls enabled on the splunk host.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;On the splunk side, I've installed Cisco Security Suite and Cisco IPS applications.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The splunk logs show it's able to connect to the host, but then throws the following error:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;URLError: &amp;lt;urlopen error Tunnel connection failed: 503 Service Unavailable&amp;gt;.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Not sure at this point if I need to configure something else before being able to add the splunk host as a trusted host?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Any info appreciated.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks.&lt;/P&gt;</description>
