Lighthouse: DevTools Error: Unable to load the page: net::ERR_EMPTY_RESPONSE

[radum]

I'm not sure if a HTTP request is made also as part of the test, if it is and the local server doesn't serve anything via HTTP this might be the reason.

Initial URL: https://local.dev:4243/live.html
Chrome Version: 61.0.3149.0
Error Message: Unable to load the page: net::ERR_EMPTY_RESPONSE

I'm witnessing the same via the Lighthouse Chrome extension. It begins to audit a local instance of my app which is served with a self-signed certificate, but then it ultimately requests it again over HTTP.

Lighthouse has an audit that will fail if an app has no HTTP-to-HTTPS redirect, so it seems that this is a bug.

Initial URL: https://localhost:3001
Chrome Version: 59.0.3071.115 (64-bit)

I can also confirm the same happens when running the extension in Chrome Canary 61.0.3150.0, as well as version 2.2.1 of the CLI.

I also see this with 1.6.5, so for now I've implemented a local redirect.

thanks for the detailed report @jamesseanwright! this does indeed seem like an instance of #1978
