Error while generating Lighthouse report

Hi @addyosmani ,

I am trying to run Lighthouse with Chrome Installer and headless mode , but we are getting this error more than often.

GatherRunner:error Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests. (Status code: 401).

We are doing this on one of our in house websites.

We have run this continuously and it seems to work 3 times our of 20 and fails rest of them. Can you please help ?
