How to reverse proxy tunnel TCP + HTTP3/QUIC?

[Ramblurr]

I am using gost as a cloudflared/cloudflare tunnel replacement using the reverse proxy tunnel method, and it works great for HTTP 1.1 and HTTP2, but I'm stuck trying to configure it for HTTP3/quick:

I guess this is possible since the documentation says:

The tunnel itself supports multiplexing. A single tunnel is not limited to a certain type of traffic, but also supports simultaneous transmission of different types of traffic (Web, TCP, UDP).

This is my service configuration.. how would you add or modify it to support HTTP3 using the same ingress?

"services": [
    {
      "addr": ":3434",
      "handler": {
        "auther": "auther-0",
        "metadata": {
          "entrypoint": ":443",
          "ingress": "ingress-0"
        },
        "type": "tunnel"
      },
      "listener": {
        "type": "tcp"
      },
      "name": "listener-0"
    }
  ],
...ingressses not included...

Basically my goal is to have gost to TCP and UDP reverse proxying with hostname routing to the final web server

I tried adding another listener with type udp...

"services": [
    {
      "addr": ":3434",
      "handler": {
        "auther": "auther-0",
        "metadata": {
          "entrypoint": ":443",
          "ingress": "ingress-0"
        },
        "type": "tunnel"
      },
      "listener": {
        "type": "tcp"
      },
      "name": "http-tcp-listener"
    },
    {
      "addr": ":3434",
      "handler": {
        "auther": "auther-0",
        "metadata": {
          "entrypoint": ":443",
          "ingress": "ingress-0"
        },
        "type": "tunnel"
      },
      "listener": {
        "type": "udp"
      },
      "name": "http3-udp-listener"
    }
  ],
...ingressses not included...

.. but that causes errors because it is trying to listen on tcp :443 again..

level=info msg="listening on [::]:3434/tcp" caller="service/parse.go:327" handler=tunnel kind=service listener=tcp service=http-tcp-listener
level=error msg="listen tcp :443: bind: address already in use" caller="tunnel/handler.go:143" handler=tunnel kind=handler listener=udp service=http3-udp-listener
