Good evening All

I am facing a small issue, could you please let me out

This works if i allow unencrypted is true : Set-Item -Path WSMan:\localhost\Service\AllowUnencrypted -Value true

**Error: fatal: [[win-client-01.adc1.com](http://win-client-01.adc1.com/)]: UNREACHABLE! =\> {“changed”: false, “msg”: “kerberos: Bad HTTP response returned from server. Code 500”, “unreachable”: true}**

Note: I have not done any configuration on windows host node( default winrm service is running and firewall is disabled)

I ran into this. Upgrading the python modules _pykerberos_ and _pywinrm_ fixed it for me.
