Unable to run ansible command using aws ec2 dynamic inventory

[Ravi Tiwary]

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.
