Error when using Httpoison/hackney with github

For a project I am using Httpoison.Async in stream_to in order to handle large files without loading the download in memory first. However, I am experiencing an issue which seems to only affect downloading a redirected link to Github. Could not find the same issue using Google. Has anyone experienced this before and knows a solution?

Relevant code which triggers the error: https://github.com/benoitc/hackney/blob/5b51fb82547dd3a492aaac5d63f7aa1ada1e65cf/src/hackney_stream.erl#L29
