Erlang v. 23.0 and HTTPoison error
Dear all,
After upgrading Erlang to version 23.0, a previously working project stopped working and I am getting the following error when the HTTPoison is called:
** (MatchError) no match of right hand side value: {:error, %HTTPoison.Error{id: nil, reason: {:options, {:sslv3, {:versions, [:“tlsv1.2”, :“tlsv1.1”, :tlsv1, :sslv3]}}}}}
Does anyone else get a similar behaviour? Any hints for a solution?
Thanks in advance for your help!

Thank you for the hint!
I would like to elaborate a bit more here to assist others facing a similar problem.
I have changed mix.exs by adding in deps:
{:hackney, github: “benoitc/hackney”, override: true}
Moreover, I have modified the usage of HTTPoison to set the options, e.g.:
options = [ssl: [{:versions, [:“tlsv1.2”]}]]
{:ok, %HTTPoison.Response{body: body, headers: _headers}} =
HTTPoison.get(, [], options)
(UPDATE)
It seems that the change in the mix.exs file is not necessary.

Now that hackney 1.16.0 is released, we can get the fix into projects with:
$ mix deps.update hackney
In my project this gives me:
Upgraded:
certifi 2.5.1 => 2.5.2
hackney 1.15.2 => 1.16.0
idna 6.0.0 => 6.0.1
ssl_verify_fun 1.1.5 => 1.1.6
unicode_util_compat 0.4.1 => 0.5.0 (minor)
* Updating hackney (Hex package)
* Updating certifi (Hex package)
* Updating idna (Hex package)
* Updating ssl_verify_fun (Hex package)
* Updating unicode_util_compat (Hex package)
And TLS HTTP requests are once again working. Thanks!

Downgrade to OTP 22.x or get Hackney from master. See https://github.com/benoitc/hackney/pull/619

First guess: tlsv1.3 was added and sslv3 was removed in OTP 23 according to the release notes.
