    I'm able to work around this (or a similar) issue by tethering via USB from my Pixel while connecting with the AWS VPN client. I would get this error:

    The VPN connection is being terminated due to a discrepancy between the IP address of the connected server and the expected VPN server IP. Please contact your network administrator for assistance in resolving this issue.

    Presumably from this requirement which is relatively new:

    The Client VPN service requires that the IP address the client is connected to matches the IP that the Client VPN endpoint's DNS name resolves to. In other words, if you set a custom DNS record for the Client VPN endpoint, then forward the traffic to the actual IP address the endpoint's DNS name resolves to, this setup will not work using recent AWS-provided clients. This rule was added to mitigate a server IP attack as described here: TunnelCrack.

I'm able to VPN via a tethered connection on my TMobile account again - this issue is resolved for me using the 3.12.2 AWS VPN Client. I'm fairly certain TMobile worked it out on their end, since I don't believe I've updated my client since the last time I checked and it didn't work.
