Are you accessing it on the same LAN or network segment? Or, are you trying to access it remotely where NAT might be an issue? If you are able to access it locally, but not remotely, make sure that the firewall/router is routing outbound and inbound traffic via the same WAN IP address. Sometimes, an inbound NAT rule will map 7071 to right internal IP address, but will not route the traffic out through the same link... in this scenario, your local system will throw a fit because it is expecting the traffic from the same IP it sent it to.
Anyhow, I hope some of that helps.
