##### ANSIBLE VERSION
```
ansible 2.9.1
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/etsadm/.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, Jun 11 2019, 14:33:56) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
```

##### CONFIGURATION
```
DEFAULT_FORKS(/etc/ansible/ansible.cfg) = 30
DEFAULT_LOG_PATH(/etc/ansible/ansible.cfg) = /var/log/ansible/ansible.log
DEFAULT_ROLES_PATH(/etc/ansible/ansible.cfg) = [u'/etc/ansible/roles', u'/usr/share/ansible/roles']
DEFAULT_VAULT_PASSWORD_FILE(/etc/ansible/ansible.cfg) = /home/etsadm/ansible_pwd.txt
HOST_KEY_CHECKING(/etc/ansible/ansible.cfg) = False
```

Dynamic inventory created with these variables for all nodes:

'all': {
        'vars': {
            'ansible_winrm_cert_pem': '/etc/ansible/certificado/cert.pem',
            'ansible_winrm_transport': 'certificate',
            'ansible_winrm_server_cert_validation': 'ignore',
            'ansible_winrm_cert_key_pem': '/etc/ansible/certificado/key.pem',
            'ansible_connection': 'winrm'
        }
    }

##### OS / ENVIRONMENT
RHEL 7.7 x86_64
Ansible 2.9.1
Python 2.7.5

##### STEPS TO REPRODUCE

Every ad-hoc command executed on a Windows node, connecting by WinRM and certificate,  throws an exception but command runs fine.

Example:
<!--- Paste example playbooks or commands between quotes below -->
``` ansible -m win_ping windows_node_client ```

##### ACTUAL RESULTS
```
