Download Fails on 0.2.0

[MyklClason]

Not sure if this an issue with this gem or CloudConvert API. However, the web app I work on as a developer is no longer able to download converted files due to this error (removed the stack trace before the code was ran within the app).

Errno::ECONNREFUSED: Failed to open TCP connection to :443 (Connection refused - connect(2) for nil port 443)

Here is the code I'm using:

    def convert_file(inputformat, outputformat, file)
      @client = CloudConvert::Client.new(api_key: ENV['CLOUDCONVERT_API_KEY'])
      @process = @client.build_process(input_format: inputformat, output_format: outputformat)
      @process_response = @process.create
      if @process_response[:success]
        @conversion_response = @process.convert(
          input: "upload",
          outputformat: outputformat,
          file: file,
          download: "false")
        if @conversion_response[:success]
          @download = @process.download(zoho_download_folder)
        else
          raise "Conversion failed => Response: #{@conversion_response}"
        end
      else
        raise "Could not obtain a process => Response: #{@process_response}"
      end
    end

It is used like this:

converted_file = convert_file('xls', 'csv', file)

The file is a 9.5MB xls file downloaded from zoho docs, which doesn't allow CSV downloads, at least at the time this solution was developed.

I have confirmed that this issue started after CloudConvert did a software update about 2 days ago. From the logs I determined this:

Last time the process run was at:
Sun, 17 Jun 2018 12:01:52 +0000

CloudConvert Software updated at
Sun, 17 Jun 2018 15:00:00 +0000 (about 3 hours later)

Next daily run, the app failed to Import at:
Mon, 18 Jun 2018 13:01:19 +0000

I'll also be submitting this to CloudConvert as well.
