Buildbot tutorial failure - worker can't connect to master - buildbot

Question

I'm trying out buildbot, and following the tutorial. I successfully installed and started the master, as shown from the twistd.log partial file below.

After installing and setting up the worker, the worker fails to connect to the master, and I'm also unable to load localhost:8010 as the tutorial indicates should be running. I've verified that I created the worker with the same worker name and password as the master.cfg file specifies. Any thoughts on what I missed?
A partial worker twistd.log is below:

Please, try use buildbot reconfig (http://docs.buildbot.net/1.5.0/manual/cfg-intro.html?highlight=reconfig)
or buildbot upgrade-master (http://docs.buildbot.net/1.5.0/manual/cmdline.html?highlight=upgrade-master#)
Also, You can find a reference to reconfig in the Buildbot Quick Tour: (http://docs.buildbot.net/1.5.0/tutorial/tour.html)
You should use this after each changes in your Buildbot decision (workers, schedules, notifiers, factories, etc...)
