This is the fact gathering step, as you can see from the output, only 1
of 13 hosts are reachable

Since you have 12 unreachable host your loop will have 12 undefined
variables.
In the first iteration
hostvars[item]['ansible_default_ipv4']['address']
will be
hostvars['openam-instance']['ansible_default_ipv4']['address']
Since host openam-instance is unreachable this is a undefined variable.
To make it not fail you need to filter it through the default filter.
debug: msg={{ hostvars[item]['ansible_default_ipv4']['address'] |
deffault() }}
