Quic Protocol error when using Http/3 (with Quic)

What is the name of the domain?

What is the error message?

ERR_QUIC_PROTOCOL_ERROR

What is the issue you’re encountering

Site will not display at all when Http/3 with Quic is turned on

What steps have you taken to resolve the issue?

I turned off Http/3 with Quic and the site displays fine without it, but I’d like to figure out why it fails to load when this feature is enabled. The site uses Wordpress if that might be related (I have a few other non-Wordpress sites using Http/3 with Quic with no issues).

The site registration was only transferred to Cloudflare today so maybe I just need to wait? Apologies if that’s the case and I’m being impatient!

What are the steps to reproduce the issue?

Turn on http3 with quic

I am unable to reproduce. Are you still encountering this issue?
