I am trying to run ansible command sudo ansible -i ./dynamic-inventory/ec2.py tag\_Name\_aws\_test\_win -m win\_ping  
using module win\_ping from ansible server to remote node and it is throwing error

aws\_test\_win | UNREACHABLE! =\> {  
“changed”: false,  
“msg”: "Failed to connect to the host via ssh: ssh connect to host 172.31.1.10 port 22:

I have defined variables in yml file under group\_vars call tag\_Name\_aws\_test\_win

ansible\_user: ‘ansible’  
ansible\_password: ‘XXXXXXXXXXXXX’  
ansible\_winrm\_transport: credssp  
ansible\_port: ‘5985’  
ansible\_connection: ‘winrm’

ansible\_winrm\_server\_cert\_validation: ignore  
validate\_certs: false

Please advise if I missing something.
