But these superpowers are sometimes hindered by tedious configuration work that expects you to master yet another arcane language assembled with heaps of words youve never seen before. To establish the SSL connection directly with the backend, you need to reverse proxy TCP and not HTTP, and traefik doesn't (yet ?) I have tried out setup 1, with no further configuration than enabling HTTP/3 on the host system traefik and on the VM traefik. Traefik v2 is a modern HTTP reverse proxy and load balancer, which is used by HomelabOS to automatically make accessible all the docker containers, both on http and https (with Let's Encrypt certificate).. Exposing other services. In the traefik configuration of the VM, I enable HTTP3 and set http3.advertisedPort to the forwarded port (this will cause traefik to listen on UDP port 443 for HTTP/3 traffic, but advertise the configured port using the Alt-Svc HTTP header instead). To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is the proxy protocol supported in this case?
