Lighthouse runs fine for me on the URL you provided. The report viewer doesn't run Lighthouse, it just renders the report.

Can you provide specific reproduction steps to get this error?

Error is from PSI. https://googlechrome.github.io/lighthouse/viewer/?psiurl=https://jaccountants.co.uk/ Happened first time I tried.

Devtools logs aren't very useful. Never get a response on the protocol. just "Network.loadingFailed"

I face a similar issue with Lighthouse. The only difference is, that I see ERR_TIMED_OUT instead of CONNECTION_FAILED.

I could see the issue was raised earlier and then closed - https://github.com/GoogleChrome/lighthouse/issues/2686.

I'm trying to run the audit through the Chrome extension.

Could you please take a look at this?

[connorjclark]

The only difference is, that I see ERR_TIMED_OUT instead of CONNECTION_FAILED.

So a different issue... please open a new issue and fill out all the required information.

[alexnj]

The issue doesn't seem reproducible. Lighthouse runs fine on the URL. Closing this out, please feel free to reopen if the issue still persists.
