HTTPoison request failes on specific machine but works in another machine

Question

Am doing a post with HTTPoison, on one machine everything works well, but in the other the same code, with similar environment parameters.

HTTPoison.post!("https://remote_api", "", [{"X-TOKEN", System.get_env("API_TOKEN"}, {"Content-Type", "application/json"}])

fails with

** (HTTPoison.Error) {:options, {:sslv3, {:versions, [:"tlsv1.2", :"tlsv1.1", :tlsv1, :sslv3]}}}
    (httpoison) lib/httpoison.ex:128: HTTPoison.request!/5

both machines are setup the same running centos7, but i get expected results in one but not in the other. am not sure what i got wrong

Downgrading to OTP 22 fixed it, thanks Aleksei Matiushkin.

Answer 1

Bumping hackney to version 1.16 worked for me.

 defp deps do
    [
      ...
      {:httpoison, "~> 1.6"},
      {:hackney, "~> 1.16"}
    ]
  end

Answer 2

I'm having the same issue and it looks like this fix in hackney will resolve the problem. It's been merged to master but hasn't been released yet.

In the meantime, downgrading to OTP 22 is a good solution.

Answer 3

This works for me for the moment:

{:hackney, git: "https://github.com/benoitc/hackney.git", branch: "master", override: true}
