WebTransport (over HTTP/3) framework for Elixir

requiem's Issues

Does not work on Firefox 114

Firefox 114 introduced support for WebTransport, so I wanted to use requiem as the server.
I cloned the latest git for requiem, and in the examples/requiem_echo directory I issued the commands:

mix deps.get
CERT=/home/fri/mkcert/localhost.pem PRIV_KEY=/home/fri/mkcert/localhost-key.pem mix run --no-halt

Before doing so, I created a cert file for localhost using mkcert (in the directory /home/fri/mkcert)

mkcert install
mkcert localhost

I headed my browser to:

https://googlechrome.github.io/samples/webtransport/client.html

and used https://localhost:3000/ as the URL.

After clicking on "Connect", the Event log reads as follows:

- Initiating connection...
- Connection failed. WebTransportError: WebTransport connection rejected

Meanwhile, the stdout and the log on the Elixir side of things reads like this:

So it looks like it's connecting, but in the handshake there is a packet with a very small timeout value, so the connection times out.

Is it possible that requiem is using an older spec of the WebTransport protocol, thus it misinterprets what Firefox is sending?
