title: Error using Octave 4.0.2 to submit Coursera assignments
body: <p>This is the error:</p>
  
  <pre><code>   curl: (1) Protocol "https" not supported or disabled in libcurl
      !! Submission failed: unexpected error: input file does not exist
      !! Please try again later.

  <p>I am using Windows 10.</p>
  
  <p>I see a possibly relevant answer <a href="https://stackoverflow.com/a/31065490/4089351">here</a>, but I don't know where this code would be added within Octave.</p>
