1706586 - https://www.notebookcheck.net is often slow when http3 is enabled

Status: RESOLVED DUPLICATE of bug 1700703

(Core :: Networking: HTTP, defect, P2)

Description

[Olli Pettay [:smaug][[e-mail]]]

https://www.notebookcheck.net/ seems to be often stuck and reloading doesn't help.
But if one disables http3 and then reloads, page load works fine again.

[Jan Alexander Steffens [:heftig]]

They're also using CloudFlare so this could be related to bug 1700703?

Comment 3

[Dragana Damjanovic [:dragana]]

This is the same as bug 1700703.
I can reproduce it. I am working with Cloudflare to try to figure out what is causing this.

Thank you for reporting.

Comment 4

[Dragana Damjanovic [:dragana]]

The issue should have been fixed. I am not able to reproduce it anymore (I was able to reproduce it very reliably)
Olli and Jan, can you test if the issue has been fixed?

Comment 5

[Jan Alexander Steffens [:heftig]]

Thanks! I've re-enabled http3 and haven't managed to reproduce the problem. I'll let you know if I encounter the issue again.

The site has been working fine recently.
