MNPP is running but connection refused

[tim-peterson]

I've had my MNPP app running on localhost port 80 for quite awhile. Recently I did a software update and set up a Go app on different port and now I can't run MNPP on localhost.

I've very confused on where to start but think this is a firewall issue based on the following:

Tims-MacBook-Pro-2:html TimPeterson$ telnet localhost 80
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying fe80::1...
telnet: connect to address fe80::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host 

Pointing the browser to http://localhost gives : Oops! Google Chrome could not connect to localhost.

The reason I think this is an Issue and not just a Stackoverflow question is because if it is a permission/firewall issue, it would be nice to include the solution to this issue in the documentation so that others won't fall into the trap I've been in for the last several days.
