Great work on finding the solution. Thanks for taking the time to post an update with your findings. That is valuable information for me as a newbie to this subject of proxies.

I was also able to reproduce the issue when I set the proxy configuration via the environment variable (I was previously setting it via the Windows " **Network & Internet**" settings page).

If you do want to continue to use these environment variables, I found I was able to disable it for the `localhost` hostname specifically by defining an environment variable named `no_proxy` with the value `localhost`.
