I though :cowboy was being made available through cowboy_plug when its not... the issue remains the same with some caveats

:application.get_key(:cowboy, :vsn) |> IO.inspect() == {:ok, ~c"2.10.0"}

I can replicate the issue in my local env using self signed certs. Same error message anyway, tracing looks the same.

Various combinations of tls_ops render the same :gun error

Oh that's Websocket? For Websocket over HTTP/2 you need to enable the CONNECT protocol in Cowboy, see: https://github.com/ninenines/gun/blob/master/test/ws_SUITE.erl#L47

You cannot use Websocket until the setting is set (see the test suite for how to wait for the right moment).

Alternatively you can disable HTTP/2 in Gun if you don't need it.

The problem occurs with TLS but not TCP because TLS uses ALPN to select the protocol and that defaults to HTTP/2.
