Connecting VPN in Circleci WIndows Instance - windows

Question

I am facing this error while connecting to VPN in circleci. Has anyone encountered this ?
Context: I wanted to deploy files to AWS Windows EC2 instance and I am doing that using ssh in cirleci. In my EC2 instance, I have added inbound rule in port 22 of SSH to only allow connections from VPN connected connection only.
Edit:
Here is my config file:
