title: localhost on MacOSX connection refused
body: <p>I've had my app running on localhost port 80 via nginx on my mac for quite awhile. Recently I did some software updates and was trying to run other apps on different ports and now I can't run my first app on localhost:80.</p>
  
  <p>I've very confused on where to start but think this is a firewall issue based on the following:</p>
  
  <pre><code>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 
  </code></pre>
  
  <p>pointing the browser to <code>http://localhost</code> gives this <code>Oops! Google Chrome could not connect to localhost</code></p>
  
  <p>thoughts?</p>
