(in the reference to the middleware) with the provider namespace, Come to think of it the whoami(udp/tcp) are unnecessary and only served to complicate the issue. I was hoping I just had to enable HTTP/3 on the host system, similar to how it was when I first enabled HTTP/2, but I quickly realized that the setup will be more complicated than that. Just use the appropriate tool to validate those apps. I assume that traefik does not support TLS passthrough for HTTP/3 requests? Once you do, try accessing https://dash.${DOMAIN}/api/version Are you're looking to get your certificates automatically based on the host matching rule? This configuration allows generating a Let's Encrypt certificate (thanks to HTTP-01 challenge) during the first HTTPS request on a new domain. The polished configuration options ensure that configuring Traefik is always achieved the same way whether expressed with TOML, YAML, labels, or keys, and the revamped documentation includes examples for every syntax.
