I have a Phoenix project being developed on a desktop machine (Mac) and wanted to take it “on the go” so I installed supposedly all required packates on my laptop (GNU/Linux) but I am now getting errors from Recaptcha library

TLS client: In state certify at ssl_handshake.erl:377 generated CLIENT ALERT: Fatal - Internal Error\n {unexpected_error,undef}'}} of type Tuple[...]

I suspect this might be due to versions difference in Elixir or Erlang:

$ elixir --version
Erlang/OTP 22 [erts-10.6.4] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

Elixir 1.9.1 (compiled with Erlang/OTP 22)

Or maybe a missing package that wasn’t directly pulled as dependency?

Does any of that ring a bell? On the desktop the vesion is:

$ elixir --version
Erlang/OTP 24 [erts-12.0.3] [source] [64-bit] [smp:24:24] [ds:24:24:10] [async-threads:1] [jit] [dtrace]

Elixir 1.12.2 (compiled with Erlang/OTP 24)

These came from homebrew, while on the laptop they come from Ubuntu’s repositories of 20.04LTS.
