Hi @ycdxsb,

thanks for reporting this issue.

So the win_inet_proxy Ansible module failed to set the proxy.

The proxy value is gathered from the environment by windows.pkr.hcl

Maybe try to check if your proxy value has the expected format ? https://docs.ansible.com/ansible/latest/collections/community/windows/win_inet_proxy_module.html#parameter-proxy

If you can share your proxy variable, i could try to get a repro here.

Otherwise, running ansible with maximum verbosity should give you a hint at what's wrong. Edit windows.pkr.hcl#146 and append many -v flags to the ansible command line.

Additionaly i found a similar issue here https://github.com/ansible-collections/community.windows/issues/372

Thanks for your help, I think I have solved this issue. The problem is that the Python version of my Ubuntu 20.04 is Python 3.8, so I am using the old version of kafl.targets. This installs an old Ansible version 6.7.0 rather than 7.1.0 in the latest kafl.targets. The code related to win_inet_proxy in Ansible version 6.7.0 does not handle the exception shown above.
