Start by inspecting the failing st2 execution command and /etc/ansible/pb-win-restart-service.yml, then check the Python dependencies used for winrm and requests, including six. Reproduce the webhook-triggered playbook run and consider the issue resolved when the Windows service restart completes without the missing-module error.
