The test to the loadbalancer itself never fails, and serves the same content as the websites (although host and metadata are a bit different), and I can’t for the life of me figure out the disconnect.  
If someone can point me in the right direction it would be appreciated.

All hosts are ubuntu 16.04.01 LTS  
hostnames:  
loadbalancer - Ansible-nginx  
webcluster - AnsibleWeb, AnsibleWeb2

All AWS EC2 instances

The loadbalancer lines in my status playbook:

- hosts: loadbalancer  
tasks:

- name: verify backend index response  
uri: url=http://{{item}} return\_content=yes  
with\_items: ‘{{groups.webcluster}}’  
register: app\_index

- fail: msg=“index failed to return content”  
when: “‘Hello, from sunny {{item.item}}!’ not in item.content”  
with\_items: “{{app\_index.results}}”

Output of the play before it stops:

I am trying to figure out the same issue. Please let me know if you have it resolved.

Thanks,

from what i see {{ item.item }} would expand to 'AnsibleWeb' when the  
content actually has "ip-172-31-24-83!" hence it fails. so i think  
the condition would be  
when: "'Hello, from sunny {{hostvars[item.item][ansible\_hostname]}}!'  
not in item.content"  
you might need a play to collect facts from the web group.
