Environment

• Elixir & Erlang versions Elixir 1.16.2 (compiled with Erlang/OTP 26):
• ExAws version 2.5.1
• HTTP client version. hackney 1.20.1

Current behavior

This code that streams a file from s3 lineline works in dev mode. I'm using minio as my storage server. When I make this request in production I get the error below. The code snippet I got from the ex_aws_s3 docs on streaming files.

bucket
      |> ExAws.S3.download_file(file, :memory, opts)
      |> ExAws.stream!(scheme: scheme <> "://", host: host, port: nil)
      |> Stream.chunk_while("", &chunk_fun/2, &to_line_stream_after_fun/1)
      |> Stream.concat()

Expected behavior

I expect the code to work as does in dev. I don't know if its my nginx configuration or something else. File uploads, generating download links, getting a file object all work, so its not an issue with my credentials.
