Lighthouse Test Fails with Timeout

Support
1

I ran the following test: WebPageTest - Running web page performance and optimization tests...

Parameters: From: Ireland - EC2 - Chrome - Emulated Motorola G (gen 4) - 3GFast - Mobile

I also included the Lighthouse report, but I get the following error:

Waiting for DevTools protocol response has exceeded the allotted time. (Method: Emulation.setScriptExecutionDisabled)
LHError: PROTOCOL_TIMEOUT

As best as I can tell, the browser’s main thread was hung so Lighthouse couldn’t run the remote dev tools commands anymore. Not sure exactly why because WebPageTest itself doesn’t appear to have issues measuring the page.

Hi, I am having the same issue on all tests ran via API.

Did you find you what is causing this?
