Here is the exception (it looks similar to  crbug.com/639113  but failure point is different and ALL devices are affected now):

Sorry, this is one of my CLs

Harpreet - this should be fixed. You may need to wait for chrome to roll if it didn't last night. Please verify.

We are seeing this consistently now. Please take a look.

Its failing while waiting on "identifierId":

Looks like this is happening because of the new login flow UI. 

I just ran the test locally and it times out on the 'network not available' window even though ethernet is available.

With some run's I see the following error.

I know how to fix this, but this needs to land first: https://chromium-review.googlesource.com/#/c/391123/

This should fix this.

There seems to be an independent problem where the hotrod app is not being downloaded.

Ok. Let me patch this CL locally and try.

This works for me. It does complain that the app is was not downloaded but relaunching chrome auto launches the hotrod app and the test passes.

That's what I'm seeing too

Yes. I think this has been like this for a long time now but only happens with autotests.

Can you please submit this soon so it gets in before the M55 branch on Thursday. Otherwise the tests will continue to fail on M55 for another 6 weeks unless we merge this back after branch.

Ok, I see you've put it in the CQ. We can chump it in if the CQ fails to land this EOD.

Sure. SG

CL has landed. Please verify
