Hello,

I received an error earlier that my Ansible master unable to connect to windows hosts by throwing below error.

`  
msg": “winrm or requests is not installed: cannot import name UnrewindableBodyError”

`

by running below command

`pip install --proxy=proxyserver:80 --ignore-installed "pywinrm>=0.3.0"`

I was able to ping windows servers, however, I am still receiving the below message, which is annoying for huge inventory.

`  
/usr/lib/python2.7/site-packages/requests\_ntlm/requests\_ntlm.py:200: NoCertificateRetrievedWarning: Requests is running with a non urllib3 backend, cannot retrieve server certificate for CBT  
NoCertificateRetrievedWarning)  
x.x.x.x | SUCCESS =\> {  
“changed”: false,  
“ping”: “pong”  
}

`  
Can someone check the warning and guide me on how I can address this issue?

Thanks and Regards  
Raj
