Http/3 is not working when I removed “experimental_http3”: true

Caddy’s HTTP/3 works.

Geekflare is broken.

Use curl --http3 -v to verify.

HTTP/3 not working

I don’t recommend http3check.net by LiteSpeed. Caddy uses a newer draft of QUIC/H3 than their “LSQUIC” library supports. The GeekFlare HTTP/3 test is better. Chrome is picky about which draft it supports.
