Can you copy-paste the full error?

It seems like there's an issue with the SSL handshake. Do you have certify and ssl_verify_fun in your deps as outlined in the readme?

defp deps do
  [
    # ...
    {:pow_assent, "~> 0.4.7"},
    {:certifi, "~> 2.4"},
    {:ssl_verify_fun, "~> 1.1"}
  ]
end

Hmm, this could be due to many things.

I tested this locally and it works as expected. You can try it yourself running iex -S mix in your app dir and then call the following method:

Assent.Strategy.request(:post, "https://www.googleapis.com/oauth2/v4/token", "", [], [http_adapter: Assent.HTTPAdapter.Httpc])

It should return a Assent.HTTPAdapter.HTTPResponse struct, rather than Assent.RequestError with the handshake error.

Two questions:

1. What OTP version are you running on?
2. Do you have any :http_adapter config set? If :ssl key is set it would override the default ssl settings.

[jagoanmamah]

I don't have :http_adapter

Ok, I can reproduce it now. I was running on OTP 22.2. On OTP 23 it fails. Let me figure out why.

[danschultzer]

Assent v0.1.11 has been released. Run mix deps.update assent and it should be working again with OTP 23 😄
