We paused Cloudflare for a zone but any DNS record that’s still set to proxy has an HTTPS record that still says “alpn=h3,h2 ipv4hint=…” – the origin server doesn’t support HTTP3 though.
DNS records that aren’t set to proxy don’t have an HTTPS record.
Hi there,
Thanks for reaching out on community!
We would like to ask you a few questions.
What is your domain?
What is your expected result?
Because Cloudflare will do HTTP/3 to customers’ eyeball but forward request http1.1 or http2 to the origin.
Also, I assume the protocol optimisation was configured to http/2 and http/3 by you at Cloudflare.
Have you changed so?
When I turn on HTTP/2 and HTTP/3, my alpn change to those protocol.
