Can't connect to anything with Gun adapter using HTTP proxy #552

Tesla and Gun both with latest commits from master branch, but the same can be seen with Tesla 1.4.4 and Gun 2.0.0-rc1.

gun_client = Tesla.client([], Tesla.Adapter.Gun)
Tesla.get(gun_client, "http://icanhazip.com", opts: [adapter: [timeout: 3_000, proxy: {{127, 0, 0, 1}, 8118}]])

Running this in IEX returns {:error, :recv_response_timeout} no matter what the URL is. SOCKS proxies work fine, the problem is only with HTTP. https://github.com/ninenines/gun/issues/300 might be related, since the symptoms are similar (connection is created, but no request to end server is made).

Not a solution to your problem, but you can use httpc instead from Tesla v1.11:

def get_adapter(uri) do
  profile = uri |> to_string() |> String.to_atom()
  {:ok, _pid} = :inets.start(:httpc, profile: profile)
  :httpc.set_options([https_proxy: {{to_charlist(uri.host), uri.port}, []}], profile)
  {Tesla.Adapter.Httpc, profile: profile}
end
