:ssl.connect() always returns :socket_options error!

Since :ssl is an erlang lib I expect you would need to put the URL in single quotes for Elixir, like 'google.com'. That may not be the source of the error you are seeing but it might help.

Yup

iex(3)> :ssl.connect("google.com", 443, [{:verify, :verify_peer},{:cacerts, :public_key.cacerts_get()}])
{:error,
 {:options,
  {:socket_options,
   [packet_size: 0, packet: 0, header: 0, active: false, mode: :binary]}}}
iex(4)> :ssl.connect('google.com', 443, [{:verify, :verify_peer},{:cacerts, :public_key.cacerts_get()}])
{:ok,
 {:sslsocket, {:gen_tcp, #Port<0.7>, :tls_connection, :undefined},
  [#PID<0.244.0>, #PID<0.243.0>]}}

It’s a common gotcha when transliterating code from Erlang to Elixir.

Thanks!! That was exactly it!
