I got frustrated with Unknown CA errors from Erlang. Meanwhile, curl works just fine with the sites in question:
I get this error with both :httpc and HTTPoison.get. Here’s HTTPoison:
iex(1)> HTTPoison.get! "https://grad.tamu.edu/"
22:15:54.179 [notice] TLS :client: In state :certify at ssl_handshake.erl:2138 generated CLIENT ALERT: Fatal - Unknown CA
** (HTTPoison.Error) {:tls_alert, {:unknown_ca, ~c"TLS client: In state certify at ssl_handshake.erl:2138 generated CLIENT ALERT: Fatal - Unknown CA\n"}}
(httpoison 2.2.0) lib/httpoison/base.ex:451: HTTPoison.request!/5
iex:1: (file)
Same with thi…
I couldn’t find a working Elixir lib that uses curl. So I started this ultra-simple and naive (but tested) one.
iex(1)> CurlEx.get!("https://google.com")
"<html>...</html>"
Currently, Microsoft Edge / Windows is the supported custom User Agent:
iex(2)> CurlEx.get_with_user_agent!("https://google.com", :microsoft_edge_windows)
"<html>...</html>"

Try req. req | Hex
Req.get("https://grad.tamu.edu/") works fine over here.

That’s because the server has since been reconfigured to send the missing intermediate CA. (curl fetches missing intermediate CA certificates using the URL in the AIA extension, but Erlang’s ssl does not, also when using Mint/req)

Yep!
Pretty nice—they acted on it.
