I built my first Progressive Web App (PWA) in react js. When I click on Generate report on Chrome's Audit tab in DevTools, it is showing the message lighthouse is warming up forever.
My chrome version is 81.
What can i do to generate report?

Is it already built and running in the browser? – Drew Reese Apr 18 '20 at 08:38

yes, it is running – Banafshe Alipour Apr 18 '20 at 08:41

1You are using an IP which is blocked by Google like Iranian IP. Try to use a VPN and then generate the report. – karianpour Apr 18 '20 at 11:18

1Did you look for errors in the console? Does it work ok on this sample site? https://airhorner.com/ – Mathias Apr 18 '20 at 11:21

You may also want to try adding the extension and not use the version built into the dev tools. – Mathias Apr 18 '20 at 11:22

For me local pages work with built-in Lighthouse, and online counterparts with the browser extension (can be just a coincidence though ♂️) – Code Slicer Sep 28 '21 at 19:35

Related GitHub issue for this problem in Chrome v112: ["Lighthouse is warming up..." in Chrome M112 #15026](https://github.com/GoogleChrome/lighthouse/issues/15026); TL;DR: restart Chrome once and try again. – zcoop98 May 08 '23 at 20:29

@quickshiftin hi i'm sorry this didnt solve the issue. i have no explanation for why this worked in the first place either. this was some time back and probably a bug that was fixed. maybe some other answer here helps – cmgchess Jun 21 '23 at 07:24

no problem, I'm just noting the issue can occur on an incognito tab – quickshiftin Jun 21 '23 at 13:09

For me the problem was solved just by updating Chrome browser.

Disable these two options from chrome settings:
- Continue running background apps when Google Chrome is closed
- Use hardware acceleration when available
Relaunch chrome then try again
That works for me

We faced the same issue. We once ran the lighthouse for www.google.com, to check its functionality, and then we lighthoused our sites. It audited the site and generated the report.
If you still face the same issue, start interacting with the site while lighthouse audits, this solves the issue.
