The Release notes for the AWS Client VPN for Windows version 3.10.0 mention:
• Fixed a connectivity issue when Hyper-V network adapters are installed on the client machine.
Our VPN Client software is working fine for other users who are do not have Hyper-V network adapter installed.
But for users who are using Hyper-V network adapter, it appears that the VPN client is ignoring the Hyper-V adapters (Skipping Hyper-V Adapter) and it settles on the Loopback 127.0.0.1 connection to the user's computer. When trying to connect, the user gets a pop-up window with error state: Local area network IP address configuration was not found. Please check with your administrator.
This is what we see in the aws_vpn_client.log:

Maybe there is something else that needs to be configured on the AWS side to allow these hyper-v adapters to be used?
Thanks!
