ansible.posix.synchronize attempts to uses IPv6 on IPv4 only system

[BloodBlight]

SUMMARY

When using ansible.posix.synchronize to pull from a target that is dual stacked with both IPv4 and IPv6, where the control server only has IPv4 will fail with "No route to host" as it defaults to IPv6.

ISSUE TYPE

• Bug Report

COMPONENT NAME

ansible.posix.synchronize

ANSIBLE VERSION

ansible 2.9.27
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /bin/ansible
  python version = 2.7.5 (default, Oct  6 2023, 09:53:10) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

COLLECTION VERSION

This command fails, I assume becuase this is a RHEL 7 box, but running the newest version available:

ansible.posix:1.5.4

This is the only module installed.

CONFIGURATION

NULL

This is a new install.

OS / ENVIRONMENT

Managment:
NAME="Red Hat Enterprise Linux Workstation"
VERSION="7.9 (Maipo)"
IPv4 Stack

Target:
NAME="Red Hat Enterprise Linux"
VERSION="8.8 (Ootpa)"
Dual Stacked IPv4 & IPv6

STEPS TO REPRODUCE

ansible-playbook -i hosts collect_network_info.yml

 - name: Collect Network Interface and VLAN Configurations
   hosts: all_servers
   gather_facts: yes
   tasks:
     - name: Gather network facts
       ansible.builtin.setup:
         gather_subset: network
     - name: Save network facts to a file
       copy:
         content: "{{ ansible_all_ipv4_addresses }}"
         dest: "/tmp/network_facts.json"
     - name: Fetch facts from server.
       ansible.posix.synchronize:
         mode: pull
         src: rsync://{{ inventory_hostname }}/tmp/network_facts.json
         dest: "/root/Ansible/facts/{{ inventory_hostname }}_network_facts.json"
         dest: /root/Ansible/facts/

EXPECTED RESULTS

As the local host only has IPv4, and the logs seems to show the IPv4 in the connection error, I would assume it should use that.

ACTUAL RESULTS

The command actually uses the IPv6 address after resolving the IPv4 address.

FINAL NOTES

I am new to Ansible, sorry if I am missing something obvious.

[BloodBlight]

Correction, seems to be an issue with the documentation maybe?

Tried switching to IPs, and it gave the same error!

Using this works:

         mode: pull
         src: /tmp/network_facts.json
         dest: "/root/Ansible/facts/{{ inventory_hostname }}_network_facts.json"
         dest: /root/Ansible/facts/

Is this a problem with the documentation?
