My current hypothesis is on how traefik handles connection reuse for http2 First of all, a very useful finding is that curl, when run with the --http3 option, does not read the Alt-Svc header, but makes a HTTP/3 UDP request straight against the port specified in the URL (443 by default). curl https://dash.127.0.0.1.nip.io/api/version, curl -s https://dash.127.0.0.1.nip.io/api/http/routers|jq, curl -s https://dash.127.0.0.1.nip.io/api/tcp/routers|jq, curl -s https://dash.127.0.0.1.nip.io/api/udp/routers|jq, printf "WHO" |openssl s_client -connect whotcp.127.0.0.1.nip.io:8800 -CAfile traefik/certs/rootca.pem -quiet, printf "WHO" | nc -v -u whoudp.127.0.0.1.nip.io 9900.
