重要信息 证明从 18.3 迁移到 18.3.4 会导致此问题，迁移回 18.3 将其消除。

一切正常，直到片刻。然后它就停止工作了。

  def work do
    HTTPotion.get("https://ssl-third-party.com",
    ibrowse: [
      is_ssl: true,
      ssl_options: [
        certfile: Path.join(File.cwd!, "cert_dev.pem"),
        password: "pass" |> to_charlist,
      ]
      ])
  kết thúc

响应如下:

%HTTPotion.ErrorResponse{message: "closed"}

我从 iex shell 尝试了几个没有 Elixir 包装(hackney + ibrowse)的 erlang 库:

iex(5)> url = <<"https://ssl-third-party.com">>
iex(6)> headers = []
[]
iex(8)> payload = <<>>
""
iex(9)> options=[:insecure]
[:insecure]
iex(10)> :hackney.request(m, url, headers, payload, options)
{:error, :closed}
###
iex(1)> a = "https://ssl-third-party.com" |> to_char_list
iex(2)> :ibrowse.send_req(a, [], :get)
{:error, {:conn_failed, {:error, :closed}}}

虽然我可以连接到其他主机。

应用程序已启动，我可以从同一 session 发出请求。

连接适用于简单的 curl 请求。

Erlang 测试 - 18.3.4/19.0.2

OS X El Capitan。

UPD2

可能必须是 OSX 或 >18.3 OTP 错误:刚刚在另一台 ubuntu 计算机 Erlang 版本 18.3 上制作它并且工作正常，这个返回(Erlang shell):

httpc:request(get, {"https://ssl-third-party.com", []}, [], []).
{error,{failed_connect,[{to_address,{"https://ssl-third-party.com",
                                     443}},
                        {inet,[inet],closed}]}}

听起来您遇到了 this erlang-questions 中讨论的相同问题最近的邮件线程。
显然，SSL 应用程序在 18.3 补丁版本之间更改了密码套件配置，这可能导致此问题。

在我引用的邮件线程中，解决方案是配置 SSL 以使用 TLS 1.2，即设置

{versions, ['tlsv1.2']}

对于 SSL 应用程序。
