Looking at the source:
https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/get_url.py#L381
fetch_url is defined here:
https://github.com/ansible/ansible/blob/devel/lib/ansible/module_utils/urls.py#L1803
Which is *not* forking a cli program, it is using a python library, most
likely
I am running ansible playbooks against hosts in different networks or
firewall-zones and need to fetch confg-files from a local BitBucket server at
times with get_url TASKS. connectivoty to that BitBucket Server is challenging,
to put it nicely.
In order to troubleshoot how to make this work
