"Unable to connect to Algolia" on OTP 26+

[mweidner037]

Erlang OTP 26 changes the default settings for SSL connections (ref), which currently causes an error here:

algolia-elixir/lib/algolia.ex

Line 166 in 06c96f6

ssl_options: [{:versions, [:"tlsv1.2"]}]

The error shows up to users of this library as (MatchError) no match of right hand side value: {:error, "Unable to connect to Algolia"}. The internal error (from Hackney) is {:error, {:options, :incompatible, [verify: :verify_peer, cacerts: :undefined]}}.

I can make a PR restoring the (insecure) OTP 25 defaults if interested, though I realize this repo is not active anymore. For others encountering the issue, consider staying on OTP 25 or switching to https://github.com/WTTJ/algoliax.
