Nothing to do with HTTP auth.

I can't reproduce this on my local machine, but it would surprise me if it were somehow pyro-specific. Have you experienced this error on any other platform?

+toyoshim@, yhirano@: Perhaps y'all have ideas?

+rhalavati@: FYI.

Reproducible with Out-of-Renderer-CORS on Linux.
Not reproducible without Out-of-Renderer-CORS on Linux.

luca.bosi@, are you enabling "Out of blink CORS" (a.k.a. #out-of-blink-cors) via chrome://flags or command line flags?

Hi, Out of blink CORS is set to default. The flag, in the dev channel, is

CORS handling logic is moved out of blink. – Mac, Windows, Linux, Chrome OS, Android

#out-of-blink-cors

I'll have a look if enabling/disabling the flag changes anything

I can confirm that, once the flag is enabled, youtube videos do play.

I suppose that by default  out-of-blink-cors is disabled.

I've had a look here https://bugs.chromium.org/p/chromium/issues/detail?id=736308&desc=2 and I can say that, while enabling the flag let me play youtube video, I have faced other major issues with a webmail service and gmail itself crashed several times, so it's not a viable solution

Assigning to yhirano@ who requested feedback for further triage

Thank you. Please change the setting back to "Default".

Do you have any extensions installed? Can you try with disabling them? Can you provide a net-internals log? https://www.chromium.org/for-testers/providing-network-details

Here it is. I had previously disabled every extension.

Btw, these are the flags applied (file attached).

Thanks.

I cannot find https://googleads.g.doubleclick.net/pagead/id in the netlog attached at #12.

I see some https://*.google.video.com/* requests in the log, but nothing seem CORS requests.

+Blink>Media>Video

Can you try again with a fresh profile?

I hope these further logs can help.

The first one is with the flag set to default, the other one with cors enabled.

I can confirm that browsing as guest (which is by far the freshest profile I can figure) the issue is still there.

The only error that refers to CORS is ,"SERVICE_WORKER_FALLBACK_FOR_CORS":29

Has it got to do with PWA's implementation or am I completely missing the point?

> #15

Let me confirm:

 - You observe the issue on your profile.
 - You don't observe the issue on incognito.
 - You observe the issue on the guest profile.

Is that right?

> #17

That string looks like a constant definition for the log.

Yes, I confirm everything and the issue is still here on the newer build 68.0.3437.0

Are you using any proxies?

No proxies.

But now I have moved to the beta channel and the issue is not present any longer.
