1629163 - network.http.http3.enabled breaks various google properties

Status: RESOLVED DUPLICATE of bug 1629090

(Core :: Networking, defect)

Description

Attachment: calendar.google.com_Archive [20-04-10 13-13-10].har

The breakage is non-deterministic. Top-level loads to various google.com properties have been failing for me in non-deterministic ways. These loads can be the result of a link click (e.g., redirecting through google.com on an outbound link click from gmail.com) or when visiting a site directly in the address bar (e.g., calendar.google.com or www.google.com).

I've attached a har file (with cookies removed) for a top-level request to https://calendar.google.com that fails.

I'm having trouble reproducing. For me, AltSvc is not indicating support for h3-27, which is what we support. I'm seeing HTTP/2 but no HTTP/3 usage in network requests to logged-in google calendar. Maybe I'm on the tail end of a staged rollout? (I'm on Comcast, in Oregon.) I don't know.

Looked at HAR, didn't see anything noteworthy.
