HTTP/3 Not getting detected.?!

Hi. One of my client website not detecting HTTP/3 even though it has been enabled from cloudflare. Previously it was fine, but after changing hosting, HTTP3 not seem to be working.
Can some one tell me why is that…?!

Thank You.

There’s some HTTP/3 glitch in some zones that they’re working on.

Ok. Right. Thank You

I’ve got the same issue, but I don’t think it’s related to the issue noted above. I enabled HTTP/3 on all my zones about 2 weeks ago, and it didn’t work then (via Firefox which I’ve specifically enabled HTTP/3 on, as well as and All my zones are still showing HTTP/3 as being toggled on in the Cloudflare UI.

I’ve kept trying now and again between enabling it around 2 weeks ago and today, it’s never worked. I’ve come back to this day to see if there’s any obvious misconfigurations, but it looks correctly configured and should be working as far as I can tell.

Any ideas?
