Had the same issue with Selenium in PowerShell over corporate VPN, without VPN got "cannot find host proxy-dmz.corporate.com" instead. Turns out the hint in https://stackoverflow.com/a/70463561/2894535 was correct, but I had to set environment variables BEFORE loading the DLL. If the DLL is already loaded, you need to quit PowerShell and start new instance.

# This works
Remove-Item 'env:http*_proxy'
Add-Item -LiteralPath 'WebDriver.dll'
$driver = [ChromeDriver]::new()

# This also works
$env:NO_PROXY = 'localhost'
Add-Item -LiteralPath 'WebDriver.dll'
$driver = [ChromeDriver]::new()


# Those will not work
Add-Item -LiteralPath 'WebDriver.dll'
Remove-Item 'env:http*_proxy'
$driver = [ChromeDriver]::new()

# Or
Add-Item -LiteralPath 'WebDriver.dll'
$env:NO_PROXY = 'localhost'
$driver = [ChromeDriver]::new()

I'm work using VPN in Windows, and I solved this issue setting an environment variable.

Variable: NO_PROXY

Value: localhost

It could be the case that a process of the WebDriver is still running in the background. Fire up Task Manager to see and end it if does.
