Doubt with ERR_BLOCKED_BY_CLIENT

Hi i have a doubt about the error:

"error": { "code": 500, "message": "Lighthouse returned error: FAILED_DOCUMENT_REQUEST. 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. (Details: net::ERR_BLOCKED_BY_CLIENT)",

It is not the first time that i get this error but is the first time that i get the details ERR_BLOCKED_BY_CLIENT

The thing that blows my mind is that im only getting this error when i check the desktop version via API checking all the categories If i check mobile version the request works fine

https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=https://www.primor.eu/&key=MYAPIKEY&strategy=desktop&category=accessibility&category=performance&category=pwa&category=best-practices&category=seo

Trying to debug i found that this error only happen in desktop with the category PWA

Any idea was this is happening? And what ERR_BLOCKED_BY_CLIENT means?

Thanks!

@nhoizey #2784 is about documenting all of the ways that the page can fail to load, a never-ending problem. ERR_BLOCKED_BY_CLIENT is one of these ways that was the root of this issue.

The root cause was that the page has ~35 frames (from doubleclickads). Apparently we had a rendering budget of less than that. We’ll have a fix out in the coming weeks (whenever our next LR release is).

it came out (back ~march 2020)
