Can't get past step one

[mriley]

Hi,

I followed these instructions at  
https://ofbiz.apache.org/business-users.html#UsrInstall and I get  
nothing to work. Web browser shows;

    Safari can't open the page "https://localhost:8443/accounting";  
can't connect to the server "localhost".

In Terminal all the ./gradlew commands seem to be doing something  
because there are no errors yet also no results. Is there a way I can  
test that anything is being built/performed?

I think I'm missing something obvious but I'm not a developer.

I'm running macOS 10.14.3 Java 1.8.0_201 OFBiz 16.11.05

Where do I start to trouble shoot this?

Thanks,

Mike
