I'm trying to update the following code to use HTTPS instead of HTTP:

    getProps = Hash.new
    getProps['url'] = update_url
    getProps['verifyPeerCertificate'] = false 
    getProps['headers'] = {"Content-Type" => "application/json"}
    Rho::Network.get(getProps, url_for(:action => :httpget_callback))

This works fine and returns the following if my update_url is http:

However, if I use https for the update_url, I get the following in the return @params:

{"rho_callback":"1","body":"","error_code":"1","status":"error","headers":{"Content-Type":"application\/json","User-Agent":"Mozilla-5.0 (; RhoSimulator; RhoSimulator v5.4.0)"}}

Am I missing some 'require' or 'extensions'? I can't find anything in the docs about it.
