Git HEAD of ansible playbook is

    Merge pull request #258 from StackStorm/custom_nginx

    Custom nginx

When I try to start st2chatops, it failed to start with error messages like

systemctl status st2chatops

I can run ./bin/hubot --adapter slack from command line and I can get hubot connect to my Slack workspace.
