AWS VPN Client - Failed to disable TAP driver

[jchens1]

Hello,

We have a few Windows 10 users that had been successfully using the AWS VPN Client which uses the TAP-Windows Adapter V9. Recently, they have had issues where the client fails to connect and where it fails in the log is disabling/re-enabling the TAP client.

We're able to authenticate and connect on other test machine with their accounts so the issue is localized to their laptops. We've tried reinstalling the client and TAP adapter but run into the same issue. We haven't been able to replicate the error on test machines but the error persists on these laptops.

Driver Provider: TAP-Windows Provider V9
Driver Date: 4/23/2019
Driver Version: 9.23.3.601
