External System Contact Error

While configuring an integration gateway in integration broker I kept getting the following error when attempting to load the connectors for the gateway (which involves contacting the gateway through the gateway URL):

Integration Gateway - External System Contact Error (158,10721)

Using the DNS entry, the gateway connectors would not load, however changing the URL to use the IP address worked, e.g.:

Gateway URL =

So this indicated an issue with the DNS entry or something in that space. Further checking using the nslookup command in Windows/Linux confirmed the issue, and after making relevant changes the DNS entry resolved as expected. A final step that was required was to restart the web server after making the DNS changes.
