[FIXED] Jenkins server is not accessible by host name (ip address)

Issue

I setup jenkins on my Mac OS X with homebrew and it works just fine via http://localhost:8080 or http://127.0.0.1:8080 I couldn't access jenkins instance via hostname/ipaddress:

 1. http://myjenkinshost.local:8080
 2. http://192.168.0.100:8080

Both links are not accessible even from local computer (jenkins host itself). Same time commands ping 192.168.0.100 and ping myjenkinshost.local work just fine.

Solution

It turned out that launch agent was configured to listen only 127.0.0.1 (or localhost). To fixed that edit jenkins agent's plist:

nano /Users/admin/Library/LaunchAgents/homebrew.mxcl.jenkins.plist

and modify httpListenAddress to 0.0.0.0 instead of 127.0.0.1

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs$
<plist version="1.0">
  <dict>

      <string>/usr/local/opt/jenkins/libexec/jenkins.war</string>
      <string>--httpListenAddress=0.0.0.0</string>
      <string>--httpPort=8080</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
  </dict>
</plist>
