Look in /etc/apache2/sites-enabled/placement-api.conf (and any other
files in the same directory) and make sure you only have one proxy
configuration for the connection between apache2 and the uwsgi
process that is running under systemd.

What's could be happening is that though you have placement running,
apache is trying to talk to the wrong thing.

You can either:

* clean up the placement-api.conf file so that it only has one entry
   and restart apache2

* unstack.sh, remove the files in /etc/apache2/sites-enabled and
   /etc/apaceh2/sites-available, and rerun stack.sh

This happens when there are repeated runs of stack.sh on the same
host with insufficient cleanup between. This probably means there's
a bit of a bug in lib/placement that we could fix so that it cleans
up after itself better.

I hope this is helpful. If this wasn't it and you figure out what
was causing it please post the solution.
