Add support for HTTP/3

[pschiffe]

Description

Maybe doesn't even need to be configurable, just enable it. Requires UDP port 443.

Even though I have this enabled for Traefik as well, as the Hetzner loadbalancer itself does not support UDP yet, is there any advantage in enabling it as a default option at the moment?

Ah, you're right -- I missed that the Hetzner LB doesn't support UDP or HTTP/3.

In that case, this feature doesn’t make much sense; it could work in setups without an LB, but I don’t think it’s really worth it.

Also, this probably only concerns the LB itself -- HTTP/3 for the upstream connection between the LB and the servers likely wouldn’t add much benefit.

I’ll try asking in the Hetzner forum about HTTP/3 support for the LB; in the meantime, this feature request can probably be postponed or closed.

Great, I messaged the support team last week as well, but they just gave a generic response.

We have forwarded your feedback as a feature request to our product development team for further evaluation.
They will compare your suggestion with those of other customers and then plan the next steps for our products.

So I'm hoping that if more people request it that it will be picked up sooner rather than later🤞
