Can you run the following command
nlserver monitor -missing
Apache doesnt seem to be running?

I was able to resolve this. The documentation on the first start of the has you start then stop tomcat. And I never restarted tomcat after that. Simply running nlserver start web did the trick for http://localhost. Which then I was able to go in and create my other instances.
