The audit was working before I switched to https (vs2017 + IIS Express). The SSL certificate was auto-generated by vs2017. So I guess it's a problem with certificate validation...

@Guymestef can you reproduce with cli or extension?

Normally devtools shouldn't make a fuss about it if you "whitelisted" the ssl cert

[Guymestef]

With the extension the analysis start and after some time it's hanging up

With the CLI, the analysis succeed to complete, but Progressive Web App and Performance are wrong.
On the console logs, we can see a "time out waiting for page load".

I don't know what vs2017 did with the certificate, so I don't think it is whitelisted. I know that node is not accepting all the certificates accepted by chrome or other browsers. So the request is probably crashing with an error like CERT_UNTRUSTED or UNABLE_TO_VERIFY_LEAF_SIGNATURE.

Does iis also accept http requests or isn't it configured to host your site?

smells a bit like #2457

[Guymestef]

Only https but http is redirected to https with a code 301
